The plunger pump is reciprocating pump that use a plunger to move fluid or gas through a cylindrical chamber, this kind of pump usually is used in high-pressure hydraulic system, oil and gas industry, chemical industry and many other applications that need precise control and high-pressure pumping.

Oil and gas industry: Plunger pumps are widely used for drilling, fracking, and well stimulation. They are used to pump high-pressure fluids and chemicals into the wells to enhance the production rate.

Chemical industry: Plunger pumps are used for metering and dosing chemicals. They are used to pump chemicals into the manufacturing process at a precise flow rate.

Recently we Shenmech achieved a sales reference of reciprocating plunger pump for African customer, the pumped fluid is temperature 400c crude oil. Because of this severe operating condition, we propose selected material for plunger, liquid cylinder, crankshaft, ball valve and gland packing, also use forced water-cooling system and thermal resistance solution for stable pump performance.
