Import Depamu Vertical Reciprocating Pump — Buy in Bulk from Supplier in China

The Depamu vertical reciprocating pump is a precision fluid metering device designed for industrial applications requiring accurate, adjustable flow rates between 10 and 2000 litres per hour, with operating pressures up to 1.0 MPa. It features a patented eccentric transmission mechanism that enables 0-100% flow adjustment without mechanical backlash, and maintains a measurement accuracy of ±1%. The pump is constructed with a diaphragm made of PTFE, pump head options including PVC, carbon steel, or stainless steel, and inlet/outlet components matched to fluid compatibility. Motor power is rated at 380V, 50Hz, with options for 0.75kW or 1.5kW, and it operates within a fluid temperature range of -45°C to 450°C.

The pump's diaphragm and wetted parts are selected for chemical resistance, with PTFE as the standard material for corrosive fluids. The worm wheel is made of tin bronze, and the worm shaft is either 40Cr or 38CrMoAl alloy, ensuring durability under high torque. Bearings are sourced from NSK Japan and SKF Sweden, and oil seals are NOK Japan components, indicating use of verified international parts. The vertical motor mounting eliminates oil leakage risks, a design feature common in high-purity and hazardous fluid systems. This pump is typically used where contamination control and precise dosing are critical, such as in chemical injection or pharmaceutical metering.

This pump is widely adopted in the petroleum, fluorine chemical, and nuclear industries in China, where it holds over 90% market share in fluorine processing applications. Buyers include chemical plants, water treatment facilities, and pharmaceutical manufacturers requiring reliable, low-noise metering. The unit is shipped in a strong wooden box with pallet reinforcement, suitable for sea freight. Trade terms are typically FOB Hangzhou, with lead times confirmed upon order. MOQ is one unit, and custom configurations for material or motor power are available on request.
