The pump has two types --- horizontal single-acting and double-acting. The diaphragm separates the slurry pumped from hydraulic chamber, effectively increasing the service life of plunger (position) and packing. The diaphragm rupture signaling device prevents metered and hydraulic fluids from intermixing in case of diaphragm rupture. Under all operating conditions, the rupture of the diaphragm is reliably signaled. With appropriate wiring, the pump may be shutdown. The system remains leaktight even in case of a diaphragm rupture.

Single, duplex, and triplex diaphragm pumps are available. Capacity ≤800 m³/h, max. working pressure ≤25 MPa, slurry temperature ＜200℃, particle size ＜8 mm, concentration ≤75%.

According to individual customer requirements, safety valve, damper, check valve, circulating valve, diaphragm rupture signaling device, and control panel can be supplied in full set.
