Electric Lubrication Pump DK630 for Heavy Industry – 630Cc/Rev Helical Gear
URL slug: dk630-standard-industrial
Product Summary
The DEO DK630 is a low-noise helical external gear positive displacement pump designed for continuous lubrication and hydraulic oil delivery in heavy industrial equipment. With a displacement of 630 cc/rev, QT500 ductile iron housing, and a built-in relief valve, it ensures reliable oil supply and overpressure protection for mining, construction machinery, and steel industry applications.
Key Selling Points
- High Displacement 630 cc/rev: Delivers flow up to 200 L/min, meeting the lubrication requirements of large gearboxes and heavy machinery.
- Low Noise Helical Gear Design: Helical gear meshing reduces noise by 3 dB compared to straight gear pumps, improving workshop environment.
- Built-in Relief Valve: Adjustable 5–25 bar relief valve provides instantaneous overpressure protection, eliminating the need for external valves in basic circuits.
- Durable QT500 Housing: Cast iron pump casing ensures long service life under high pressure and harsh industrial conditions.
- Wide Viscosity Compatibility: Handles oil from 12 to 20000 cSt, compatible with thin hydraulic oil and high-viscosity grease.
