Model PZ-9 mud pump is a horizontal triplex single acting piston pump which has the advanced structure and

small in size. It has the reliable performance, good exchangeability, easy maintenance.

The pump consists of two main sections: power end & fluid end. Power end includes pump case pinion shaft,

crankshaft, back cover, connection rod, crosshead etc.

Fluid end includes valve pot assembly, valves, cylinder liners, pistons, discharge manifold and suction manifold, etc.

In order to prevent the water-hammer and reduce pressure difference in the outlet side,there fixed a discharge pulsation dampener in the discharged manifold of the pump.

In order to prevent the over-pressure, there fixed a shear safty valve in the outlet side of the pump.
