For a 50-hectare block, the Fixed DYP center pivot irrigation system and the JP800 hose reel irrigation machine are both realistic purchases — and they are not interchangeable. The Fixed DYP is a fixed center pivot irrigation system with a 395.6 m machine length that covers 50 hectares from a single pivot point, built from Q235B steel galvanized to GB/T 13912-2020, powered at 380V–460V, protected by an IP65 control enclosure, and driven by electromechanical reversible control on each span. The JP800, part of the JP90-300 series, is a hose reel irrigation machine powered by a water turbine that requires no electricity: it draws a 300 m PE pipe of 90 mm diameter, runs at 25–52 tons per hour and 0.6–0.9 MPa inlet pressure, and covers a 19–41 m spray radius.

Both machines are manufactured by China Yulin Irrigation Equipment Co., Ltd. (YULIN IRRIGATION), an irrigation machinery manufacturer established in 2009 in Lvshunkou District, Dalian City, Liaoning Province, China. The company operates a 64,653 m² production site with 152 employees and a 10-engineer R&D team, and builds center pivot, lateral move, towing and hose reel irrigation systems plus matching irrigation parts. Its equipment is exported across Australia, New Zealand, Canada, Mexico, Africa, Central Asia and Russia, among other markets, with exports accounting for about 60% of output.

The trade-off between these two machines is not quality. It is site fit. Four variables decide it: available power, field geometry, water source pressure and flow, and the operating labour model a farm can sustain. This head-to-head compares the two systems only on documented specifications, then closes with a choose-this-when framework and the purchasing terms and acceptance criteria to confirm before selecting either system.

What a 50-Hectare Decision Actually Tests

Fifty hectares is the scale at which an irrigation decision stops being about the machine and starts being about the site. Three conditions separate the Fixed DYP center pivot from the JP800 hose reel machine:

• Power. The Fixed DYP center pivot runs on a 380V–460V supply and needs that supply to exist, be sized correctly and stay stable across the field, with an IP65-rated control enclosure protecting the electrics. The JP800 is powered by a water turbine and does not require electricity at all.
• Field geometry. A center pivot works from a fixed point and covers a circular area: the DYP machine is 395.6 m long and covers 50 hectares from that point. A hose reel machine works along a lane, drawing a 300 m PE pipe of 90 mm diameter and projecting water across a 19–41 m spray radius.
• Water source. The JP800 must be matched to the source itself — 25–52 tons per hour of flow at 0.6–0.9 MPa inlet pressure. Where the source cannot deliver that pressure and flow, a water-turbine machine cannot be specified on expectation.

Why Both Machine Families Sit on the Same Shortlist Now

The global center pivot irrigation system market was estimated at USD 2.56 billion in 2025 and is projected to reach USD 5.67 billion by 2030 (Mordor Intelligence). Growth of that scale pulls two different buyer profiles into the same procurement round: large operators adding pivots to existing blocks, and remote or smaller operations looking for a machine that does not depend on the grid at all.

Major suppliers are moving in the same direction. Valmont Industries reported Agriculture segment sales of USD 278.0 million in Q4 2024, equal to 26.7% of total net sales, and Lindsay Corporation secured a multi-year international irrigation supply agreement in the MENA region valued at more than USD 100 million in 2024. Large-project demand is shifting geographically, which means buyers in power-constrained or water-constrained regions increasingly compare fixed pivots against traveler machines instead of assuming one category.

Standards matter inside that comparison. ISO 11545:2009 is the active international standard specifying an in-field method for determining the uniformity of water distribution from centre-pivot and moving lateral irrigation machines — the correct reference point when comparing declared coverage against field performance.

The Fixed DYP Center Pivot: What the Specification Says

The Fixed DYP is a fixed center pivot irrigation system in the YULIN IRRIGATION pivot range, sized so that one machine covers 50 hectares. Its documented specification contains six points that matter in procurement:

• Coverage: 395.6 m machine length covering 50 hectares.
• Structure and coating: Q235B steel, hot-dip galvanized to GB/T 13912-2020.
• Control protection: IP65-rated enclosure.
• Power supply: 380V–460V.
• Drive and control: electromechanical reversible control on each span.
• Supporting equipment: an end spray gun for supplementary irrigation and a fertilizer tank.

Two water-condition options belong in the same specification discussion. The system can include poly pipe to prevent corrosion where water is acidic or alkaline, and pesticide addition for integrated pest control. Both are stated application options, not accessories that can be assumed — they are confirmed at the specification stage.

The JP800 Hose Reel Irrigation Machine: What the Specification Says

The JP800 belongs to the JP90-300 hose reel series and is a water-turbine-powered traveler machine. Because the turbine is driven by water pressure rather than a motor, the machine does not require electricity — which is the single most important specification point for fields without a usable grid connection.

• Pipe: 300 m PE pipe, 90 mm diameter.
• Flow rate: 25–52 tons per hour.
• Inlet pressure: 0.6–0.9 MPa.
• Spray radius: 19–41 metres.
• Nozzle diameter: 16–22 mm.
• Spray gun: DL50/SIMA10497.
• Net weight: 2180 kg, tolerance ±30 kg.

Read together, these figures define the machine's operating envelope. A source that delivers below 0.6 MPa will not drive the turbine as specified; a source above 0.9 MPa needs regulation rather than a larger machine. The 19–41 m spray radius and 16–22 mm nozzle range determine the wetted width of each lane, and the 2180 kg net weight drives transport planning, lane preparation and pipe handling on site.

Step-by-Step: Matching Either Machine to a 50-Hectare Site

Step 1 — Audit power availability before anything else

Confirm whether a 380V–460V supply can be delivered to the pivot point and maintained across the season. If it can, the Fixed DYP center pivot is technically available to the project, and its IP65 control enclosure and electromechanical reversible control per span become procurement details. If it cannot, the JP800 becomes the working assumption because it uses a water turbine and requires no electricity.

Step 2 — Map field geometry and boundary losses

Draw the actual boundary and check it against a 395.6 m machine radius for the DYP. Where the block is square and contiguous, a fixed pivot delivers the full 50-hectare coverage. Where the block is irregular, split by roads or divided into strips, the lane-based pattern of the JP800 — 300 m PE pipe, 19–41 m spray radius — matches the boundary without reshaping the field.

Step 3 — Measure the water source, not the pump label

For the JP800, measure pressure and flow at the machine inlet under working conditions and compare against 0.6–0.9 MPa and 25–52 tons per hour. For the DYP, confirm the supply can sustain pivot operation plus the end spray gun for supplementary irrigation. If the water is acidic or alkaline, specify poly pipe; if integrated pest control is required, confirm pesticide addition at the same time.

Step 4 — Decide the operating pattern and labour model

The DYP operates from a fixed point using span-level reversible drive, so the machine path stays in place season after season. The JP800 irrigates along a lane and is repositioned between lanes, so the labour model is built around lane changes and pipe handling. Neither pattern is inherently less work; they distribute work differently across the season, and the farm's available labour should be compared against both honestly.

Step 5 — Confirm supporting equipment and materials

Both machines have supporting equipment documented in their applications. The center pivot machine requires supporting equipment such as an end spray gun and a fertilizer tank. The hose reel application requires supporting equipment such as a center pivot irrigation machine with end spray gun and fertilizer tank where it is used as part of a combined system. Poly pipe is specified where water acidity or alkalinity would otherwise attack the system.

Step 6 — Confirm commercial terms and acceptance criteria

Before signing, lock the commercial package: MOQ of 1 unit, delivery terms of FOB / CFR / CIF, acceptance criteria of a pre-shipment test, and payment terms of a 30% deposit after contract confirmation with the balance by T/T before shipment (L/C or D/P for the Algeria market). These terms apply to either machine.

Use Cases: Which 50-Hectare Site Gets Which Machine

Site A — Square block with existing power

A contiguous 50-hectare block with a 380V–460V supply and a permanent pivot point is the design case for the Fixed DYP center pivot: 395.6 m of machine covering 50 hectares, Q235B galvanized structure to GB/T 13912-2020, IP65 control protection and span-level electromechanical reversible control. The end spray gun and fertilizer tank extend the machine beyond irrigation alone.

Site B — No grid power, pressurised water available

Where there is no usable electricity but the source delivers 0.6–0.9 MPa at 25–52 t/h, the JP800 is the practical machine. The water turbine removes the electrical connection entirely, the 300 m PE pipe of 90 mm diameter defines the working lane, and the 19–41 m spray radius sets the wetted width.

Site C — Irregular boundary or split plots

Fields divided by roads, canals or property lines rarely match a circular coverage pattern. In that situation the JP800's lane travel follows the plot as it actually exists, and the 300 m pipe length determines how far one lane position reaches.

Site D — Aggressive water chemistry

Where irrigation water is acidic or alkaline, corrosion protection becomes a specification item rather than an afterthought. Poly pipe is the documented option to prevent corrosion from water acidity or alkalinity on the center pivot application, and it should be confirmed at the same time as the supporting end spray gun and fertilizer tank.

Site E — Combined operation on one farm

The two machine families are not mutually exclusive. The hose reel application can be supported by a center pivot irrigation machine with an end spray gun and a fertilizer tank, which means a farm can use the pivot as the base machine and place the hose reel where the fixed circle does not reach — corners, extension blocks or a second water source.

Choose-This-When: A Decision Framework

Choose the Fixed DYP center pivot irrigation system when:

• A 380V–460V supply can be delivered to the pivot point and maintained in season.
• The 50-hectare block is contiguous and can accommodate a 395.6 m machine radius.
• The farm wants a fixed machine path with span-level electromechanical reversible control.
• An end spray gun for supplementary irrigation and a fertilizer tank are part of the plan.
• Water chemistry requires poly pipe, or integrated pest control requires pesticide addition.

Choose the JP800 hose reel irrigation machine when:

• No electricity is available, or extending a 380V–460V supply is not practical.
• The source reliably delivers 0.6–0.9 MPa inlet pressure at 25–52 tons per hour.
• The field boundary is irregular, split or better served by lane-based coverage.
• A 300 m PE pipe of 90 mm diameter and a 19–41 m spray radius fit the plot's dimensions.
• The operating model can accommodate machine repositioning between lanes.

Where neither set is fully met — for example, power exists but the boundary cannot support a fixed circle — the answer is usually combination rather than substitution, with the pivot as the base machine and the hose reel covering what the circle misses.

Frequently Asked Questions

Bottom Line for a 50-Hectare Block

The Fixed DYP center pivot and the JP800 hose reel machine solve the same 50-hectare problem from opposite directions. The DYP uses fixed geometry and a 380V–460V supply to cover a circular block with span-level electromechanical reversible control, Q235B galvanized structure to GB/T 13912-2020 and IP65-protected control. The JP800 uses water pressure instead of electricity to irrigate lanes, drawing a 300 m PE pipe of 90 mm diameter at 25–52 t/h and 0.6–0.9 MPa with a 19–41 m spray radius.

If the field is square, power is available and the pivot point is permanent, the Fixed DYP is the higher-coverage choice. If power is absent, the boundary is irregular or the block is split, the JP800 is the practical choice — and the two can run together, with a center pivot machine, end spray gun and fertilizer tank supporting the hose reel application. What actually decides the purchase is documentation: measured pressure and flow at the source, confirmed power at the field, machine dimensions checked against the real boundary, and commercial terms confirmed in writing.
