Spare parts and various equipment | 3 PU 20 Triplex Plunger Pump

Destination:

The triplex plunger pump 3 PU 20 type is designed to produce the hydraulic energy and realize 36,8 l/min theoretical output at 500 rpm, providing the hydraulic energy at 140 daN/cmp max. working pressure in 6 minutes.
Working medium: nonabrasive and noncorrosive fluids ( oil, glycerine, oil products).

Constructive characteristics

The triplex plunger pump 3PU 20 type is one compact assembly, with Hydraulic body, Crank shaft and Connecting rods performed by forged steel with high andurance and the frame by welding, which provide one high stiffnes.
The Fluid end is provided with horizontal suction valves.
The construction of pump admit to all internal components.
