High pressure plunger pump with competitive price compact vertical pumps

1. High pressure pump adopts forced lubrication and cooling system to ensure long-term stable operation of power end;

2. The crankshaft box of the power end is cast with ductile iron, and the cross head slide is made of cold-set alloy sleeve technology, which is wear-resistant, low noise and compatible high precision;

3. Fine grinding of gear shaft and gear ring surface, low running noise; Use with NSK bearing to ensure stable operation;

4. The crankshaft is made of American standard 4340 high quality alloy steel, 100% flaw detection treatment, forging ratio 4:1, after survival, the whole nitriding treatment, compared traditional 42CrMo crankshaft, strength increased by 20%;

5. The pump head adopts high-pressure/water inlet split structure, which reduces the weight of the pump head and is easier to install and disassemble on site.

6. The plunger is tungsten carbide material with hardness higher than HRA92, surface accuracy higher than 0.05Ra, straightness and cylindricity less than 0.01mm, both ensure hardness and wear resistance also ensure corrosion resistance and improve service life;

7. The plunger self-positioning technology is used to ensure that the plunger is stressed evenly and the service life of the seal is greatly extended;

8. The stuffing box is equipped with imported V-type packing to ensure the high pressure pulse of high pressure water, long life;
