High-pressure process hose diaphragm pump with a specially-designed pump head structure are especially suitable to transfer fluid with a high solid content such as coal water slurry, ore pulp, etc.

Working Principle

The driver drives the crankshaft after speed reduction and torque increase in the reducing mechanism, the crank connecting rod mechanism converts rotary motion of crankshaft to reciprocating motion of piston, which pushes hydraulic oil in hydraulic chamber. Hydraulic oil transmits piston thrust force and volumetric change, acting on hose diaphragm. Hose diaphragm is subject to cyclical squeezing under force transmitted by hydraulic oil, leading to cyclical compression and relaxation of internal fluid chamber in hose diaphragm, thus producing volumetric change. Continuous fluid delivery is realized under combined action of inlet and outlet check valve assemblies.

Features

● Especially suitable for delivery of highly viscous fluids with particles based on direct-through wetted end and pump head cavity without any untouched part;

●Roller bearing used in connecting rod, allowable running at a low speed (rated speed＜60 r/min), low linear speed of piston, uneasy fluid cavitation;

● Avoided contact of fluid with pump head under separation by hose diaphragm, no wearing and no leaking;

● Modular design and inlet and outlet valve jacket design, which facilitate maintenance;

● Large capacity, low pulsation and high discharge pressure;

● Real-time detection of operation status with hose diaphragm rupture alarm function;

● Automatic/manual draining control system realizes fast equipment draining and oil make-up, rendering convenient and time-saving operation.
