KQZ2800M Plunger Pump, reciprocating five-cylinder piston pump
KQZ2800M pump is a new type of reciprocating five-cylinder piston
pump. The maximum input power of the pump is 2800HP. The pump is widely used for high power fracturing in intermittent
oil Wells.
Main structural features:
1. It is composed of three parts: power end assembly, hydraulic end
assembly and planetary gear reducer;
2, long stroke, low stroke frequency, connecting rod load, specially designed for ultra-deep oil and
gas well fracturing construction, compared with other similar
products, weight reduced by 10%, avoid the vehicle overweight;
3, external planetary gear reducer, large transmission ratio, high
transmission efficiency, smooth operation, low noise, small impact
on the internal parts of the big pump, long service life of parts;
4. Hydraulic end adopts EWS design, the hydraulic end and the power
end are connected with 20 alloy steel rod, when the hydraulic end
is removed, the rod stays 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 three different
specifications of plunger (4", 4.5", 5"), in order to obtain
different pressure, displacement for customers to choose the use.
