Double-Diaphragm Plunger Pump

1. Product Features

Double-diaphragm plunger pump transfer50% of the solid & liquid mixture materials (solid materials≤1.5mm) by high pressure. The pressure arranged 0-80 kg and the flow 1-15 tons/hour.

 Product type

double -diaphragm plunger pump

single -diaphragm plunger pump

plunger pump

diaphragm pump

Product performance

solid & liquid mixture materials transported by high pressure

Pressure: 0-80 kg0-8Mpa

liquid material transported by high pressure

Pressure: 20 kg - 2000 kg (2-200Mpa)

solid material transported by low pressure

Pressure: ≤6 kg (0.6mpa)

if diaphragm broken, the sensor sends stop-signal and avoid materials entering into transmission assembly.

Pressure unit:

1kg / 2 ≈ 0.1Mpa

=longitudinal transport distance 10 m

=horizontal transport 100 m



 Working principle

Upgraded ! !    Double-Diaphragm Plunger Pump

(1) Laser reflector is installed between the two layers of diaphragm. Under normal working status, the receiver will output normal signals.

(2) If diaphragm broken, the materials enter into interval of the layers of diaphragm, and the laser reflector will output abnormal signals, instruct pump to stop working.

Single-Diaphragm Plunger Pump 


(1)By the eccentric wheel (no. 1) rotates, three plungers (no.2) are alternately pushed.

(2) The plungers push three diaphragm by turns (no. 3).

(3)The diaphragms exert pressure to the liquid.

(4) The valve plates and valve seats (no. 4 and no. 5) of the pump make same function as one-way valve, making open-close working condition, and make liquid finish enter, pressand discharge from pump.

3.  Advantages of Double Diaphragm Plunger Pump

Double-Diaphragm Plunger Pump

(1)Double-diaphragm plunger pump equipped with automatic diaphragm broken detector and automatic alarm device.

(2)If diaphragm broken, the pump stopped working immediately, and will not damage pump by entering materials into transmission assembly.

(3)Double diaphragm plunger pump avoid oil leakage during replacement and disassembly

Single Diaphragm Plunger Pump

(1) The wearing parts contains valve plate, seat and diaphragm, which can be replaced quickly.

(2) Upgraded plunger spring is durable, not broken.

(3) By changing speed of motor, the flow and pressure can be adjusted.

(4) When flowun changed, the pressure can be modified separately by adjusting the outletvalve.
