- It consists of two assemblies: power end assembly and fluid end assembly.
- The crankshaft adopts a double-key eccentric wheel structure. Two pairs of involute helical gears are mounted on both ends of the crankshaft to transmit power and offset axial force. The large and small gears are arranged inside the pump housing, which maximizes the effective space, reduces the overall width of the pump and facilitates pump layout design.
- With light weight, compact structure and high working pressure, the pump is applicable to small fracturing trucks and skid-mounted fracturing units.
- The fluid end and power end are connected by 8 alloy steel tie rods. The tie rods stay on the power end when removing the fluid end. The plunger is connected to the crosshead via threads, allowing easy disassembly and maintenance of the fluid end.
- The fluid end assembly can be fitted with plungers of seven different specifications (2.75 in, 3 in, 3.5 in, 3.75 in, 4 in, 4.5 in, 5 in) to deliver various pressure and displacement options for customers.

3. Accessories and requirements:
1000 Quintuple PumpThe 1000HP pump assembly is mainly composed of power end assembly, fluid end
assembly, reduction box assembly, power end lubrication pipeline and reduction box lubrication pipeline and other parts.
90% mechanical efficiency, 100% volumetric efficiency - only for intermittent duty.
Note: The pump operates intermittently under the highest pressure condition, the continuous working time shall not exceed 1 hour, and the continuous working time of the pump shall not exceed 3 hours under 80% of the highest pressure condition, which is beneficial to prolong the service life of the equipment, ( The same applies to drilling fluids).
Plunger diameter selection:
3.1. Power end assembly:
The power end assembly is mainly composed of: crankshaft, connecting rod, crosshead, connecting rod pin, copper tile, small tie rod, bearing, power end housing, etc.
3.1.1, power end shell
Heat treatment of high-strength steel after welding to relieve stress
Precision boring processing
3.1.2. Crankshaft
Integral type, the material is alloy steel forging.
