KQZ2500 Plunger Pump, reciprocating, positive displacement, single
acting, horizontal five cylinder piston pump
KQZ2500 pump is a reciprocating, positive displacement, single
acting, horizontal five cylinder piston pump, the pump's maximum
input power is 2500HP. The pump is widely used in intermittent fracturing operation.
Main structural features:
1. It consists of two parts: power end assembly and hydraulic end
assembly;
2. Integrated crankshaft structure, heavy cylindrical roller
bearing support, two pairs of involute gears are installed at both
ends of the crankshaft to transfer power, reduce transmission
noise, prolong gear life;
3, the pump is light weight, small volume, high pressure, high
market share, is the standard product of large fracturing truck,
has been widely used in the market;
4, the hydraulic end and the power end are connected with 20 alloy
steel rod, when the hydraulic end is removed, the rod is left on
the power end. The plunger and small connecting rod are connected by clamp, which
makes it convenient to disassemble and maintain the hydraulic end.
5, the hydraulic end assembly is installed with four different
specifications of the plunger (3.75", 4", 4.5", 5"), in order to
obtain different pressure, displacement for customers to choose.
