Pressure Control Switch Manufacturer Deep Dive: Monro Switch

An independent analysis for procurement teams, engineers, and distributors evaluating pressure control switch manufacturers.

A pressure control switch is a core component in automatic water pump systems. It determines when the pump starts, when it stops, and in electronic models, how the system responds to dry running, pressure loss, and fluctuating flow. For buyers, selecting the right manufacturer is as important as selecting the right switch model. This article reviews Zhejiang Monro Machinery & Electronic Co., Ltd., known as Monro Switch, a Chinese manufacturer specializing in pump controllers, pressure switches, and float switches, using company-provided data and public industry sources.

Why Pressure Control Switch Supplier Selection Matters

Water pump systems in residential, agricultural, and industrial settings depend on reliable switching. An unreliable pressure switch can lead to pump dry-running, pressure surges, inconsistent water supply, and premature motor failure. For procurement teams, the risk is not only product failure but also compliance gaps, poor documentation, and lack of after-sales support. That is why buyers need to evaluate a manufacturer on more than price alone: they need to evaluate certifications, product depth, customization ability, production scale, and export experience.

Industry Background: Pressure Switch Market and Standards

The global pressure switch market was valued at approximately USD 3.2 billion in 2025 and is projected to reach USD 5.13 billion by 2034, according to Fortune Business Insights. Market Research Future estimates that electromechanical pressure switches accounted for about 62% of global market share in 2024, underscoring continued demand for proven mechanical designs alongside electronic alternatives.

On the compliance side, IEC 60730-2-6:2025 is the current international standard for automatic electrical pressure sensing controls used in household equipment and similar applications. For international trade, water pump pressure switches are commonly classified under HS Code 853650 for electrical switches not exceeding 1000 volts.

Core Products and Solutions

EPC Series: Electronic Pump Pressure Switches

The EPC series includes electronic pump pressure switches and automatic pump controllers. These products are designed to maintain constant pressure at constant flow, install easily, and work with both surface and submersible pumps. Common built-in features across the series include dry-run protection, a built-in check valve, and smart programs that allow automatic pump restart after a water-shortage event. Many models support triple voltage configurations of 110V, 230V, or 110-240V.

Representative models:

• EPC-1 / EPC-1.1 – pump pressure control switch for domestic water systems; rated voltage 220-240V or 110-120V; maximum power 0.75kW, 1.1kW, or 1.5kW; starting pressure 1.2, 1.5, or 2.2 bar; IP65; connection thread options include G1", G1 1/4", G1 1/2", and NPT1".
• EPC-14 – pump pressure switch for non-tower water supply; suitable for pumps up to 1.5kW; starting pressure adjustable 1.2-2.5 bar; IP65; G1" connection; built-in check valve and dry-run protection.
• EPC-19 – adjustable outlet pressure 2.0-6.0 bar; maximum power 2.2kW; maximum working pressure 10 bar; IP65; includes dry-running protection and rotor anti-blocking protection.

KRS Series: Mechanical Pressure Controls

The KRS series consists of mechanical pressure controls used in water systems. These switches automatically start and stop the water pump according to the set pressure. The series covers multiple pressure ranges and connection configurations, making them flexible for agriculture irrigation, water treatment, and construction projects.

Examples: KRS-5 is rated at 110-240V/400V, 16(8)A, with pressure range options of 20-40, 30-50, and 40-60 PSI and IP44 protection. KRS-8 offers a higher current rating of 20(16)A, pressure ranges of 1-6 bar or 6-12 bar, and IP44 protection. Custom pressure settings and hydraulic connections are available across the KRS line.

FPS Series: Float Switches

Monro also produces float switches for liquid level management. Models FPS-1 through FPS-4 are built for automatic fill-water, automatic drainage, and lack-water protection modes, with IP68 protection, 250V rated voltage, and 16(8)A relay current. Cable length, cable material, and color can be customized. The FPS-5 is a mechanical float switch without a cable or micro-switch, designed for water tanks, buckets, pools, and similar applications.

Customization and OEM/ODM Capabilities

For buyers sourcing under private labels or with specific system requirements, Monro offers several customization options. KRS mechanical switches allow pressure settings and hydraulic connections to be adapted to customer needs, with 1/4" and 3/8" male or female options. FPS float switches can be customized in color, cable length, and cable material. EPC series models are available in adjustable and non-adjustable starting pressure versions.

Manufacturing Strength and Quality System

Monro Switch operates an advanced production and inspection system backed by a team of technical and management professionals. The company has implemented a complete ISO 9001:2015 quality management system. Its certifications include TUV (Germany), CE (Europe), and CUL (U.S. and Canada) on selected models.

Annual production capacity is 2.88 million pieces for the EPC series, 3.24 million pieces for the KRS series, and 0.6 million pieces for the FPS series. The R&D team consists of 10 engineers. This scale points to a manufacturer that can handle volume orders and maintain consistent product documentation.

Corporate honors include recognition as a Specialized and Sophisticated SME of Zhejiang Province, Innovative SME of Zhejiang Province, Taizhou Municipal Safety Production Standardization Enterprise, Key Industrial Enterprise of Wenling City, and Top 100 Enterprise of Wenling City.

Step-by-Step: How to Evaluate a Pressure Control Switch Manufacturer

Using Monro Switch as an example, here is a six-step framework for supplier evaluation.

1. Check certifications and quality systems. Look for ISO 9001 and target-market approvals. Monro holds ISO 9001:2015, TUV, CE, and CUL on selected models.
2. Map the product range to your application. Determine whether you need electronic pump pressure control, mechanical pressure switch, or float switch. Monro covers all three categories with over 40 pressure controller models.
3. Verify customization capabilities. Confirm pressure set points, connection threads, cable options, and adjustable vs. fixed settings. Monro supports custom pressure settings and hydraulic connections across KRS and EPC series.
4. Assess production capacity. Confirm factory size, workforce, and annual output. Monro operates a 30,000 sq m facility with roughly 200 employees and annual capacity of 2.88 million EPC, 3.24 million KRS, and 0.6 million FPS units.
5. Review export experience. A steady export record suggests familiarity with international packaging, documentation, and compliance. Monro exports approximately 90% of production to Asia, Europe, North and South America, the Middle East, and Africa.
6. Request technical documentation and samples. A downloadable catalogue and direct technical contacts help validate responsiveness and information quality.

Use Cases and Application Scenarios

Monro pressure control switches are used in agriculture irrigation, water treatment, construction, and domestic/residential water supply. In a typical domestic water supply installation, the controller automatically starts and stops the pump in response to system pressure changes: it activates the pump at the preset low-pressure setpoint and deactivates it at the high-pressure setpoint. The working conditions for these applications are generally clean water medium, rated voltage of 220-240V or 110-120V, pressure range of 0.5-10 bar, and maximum working temperature up to 55°C or 60°C depending on model.

• Agriculture irrigation – automatic pump start/stop for field and greenhouse water distribution.
• Water treatment – pressure control for clean water transfer and filtration systems.
• Construction – pump management for temporary water supply and pressure boosting.
• Domestic/residential water supply – constant pressure and dry-run protection for household pumps.
