Hand Operated Diaphragm Pump - China

The diaphragm pump is made of cast iron, stainless steel, aluminum alloy, plastic etc material with NBR/neoprene diaphragm, valve ball or valve seat or PTFE diaphragm, valve ball or valve seat.

The pump is driven by hand wheel.

The pump can be used to transfer the fluids or other medium which is not easy to flow.

Working principal: The hand operated diaphragm pump is a leak-free pump, which pushes the double diaphragm to reciprocate synchronously through the hand wheel.

The diaphragm deformation causes changes in volume, and the inlet and outlet one-way valve alternately opens and closes to form an alternating effect on fluid suction and pressure in the liquid cavity, so as to continuously inhale and discharge the liquid.

This pump has excellent pressure flow automatic regulation characteristics when working, in the range of working pressure can be arbitrarily set pressure, even if the outlet plug flow is zero will not be damaged.

The manual diaphragm pump is used for water lifting operation with low head and small flow.

It is composed of pump body, inlet and outlet water pipe, inlet and outlet water valve, diaphragm and push rod.

The pump body may consist of one or two pump Chambers.

A diaphragm pump having two Chambers is arranged at the center of the pump body or two separate Chambers are arranged at the outside of the two separate Chambers.

When working, the hand wheel connected with the diaphragm is operated by hand to push the diaphragm into and out of the reciprocating movement, so that the volume of the two pump Chambers expand and shrink alternately.

When the pump chamber expands, the pressure decreases, the inlet valve opens and the outlet valve closes, and water flows into the pump chamber from the inlet pipe.

When the pump chamber shrinks, the pressure increases, the inlet valve closes, the outlet valve opens, the water in the pump chamber flows out from the drain pipe, the two pump Chambers alternately absorb and drain water, and the water can be carried 0 to 20 tons per hour.

Features: Hand operated diaphragm pump can not only pump the flow of liquid, but also transport some medium difficult to flow.

The pump has many advantages of self-priming pump, shielding pump, mud pump and impurity pump and other transport machinery.

1 - No need to use electricity, safe and reliable in flammable and explosive places; 2, flow capacious, good performance of passing, allowing to pass the maximum particle diameter of 10mm.

Pumping mud, impurities, the pump wear little; 3 - Head and flow can be stepless regulated by hand speed; 4 - The pump has no rotating parts and no shaft seal.

The diaphragm will completely separate the pumped medium from the moving parts and the medium of the pump.

So pumping toxic, easy to volatile or corrosive medium will not cause environmental pollution and harm personal safety; 5 - No need for irrigation and water diversion, suction height: 2m, lift head: 30m, discharge pressure ≥2kgf/cm2; 6, easy to use, reliable work, open and stop only simple shaking and stop shaking hand wheel, even due to the unexpected inert state and long time no medium operation or sudden stop, the pump will not be damaged ring; 7, simple structure, less vulnerable parts, the pump is simple structure, installation, convenient, the pump transmission medium will not contact the link and other moving parts, unlike other types of pump because of the rotor, piston, gear, blade and other parts of a single loss and then gradually decreased performance;
