Plunger Pump KTZ350

Plunger pump KTZ350 is a reciprocating, positive displacement, single-acting, horizontal three-cylinder plunger pump with a maximum input power of 350 hp. This pump is widely used in intermittent oil well operations such as acidizing, cementing, and water injection.

Особенности продукции

Main structural characteristics:

1. Primarily composed of the PG series power end assembly and the TH series fluid end assembly.

2. Features a double-key eccentric wheel structure for the crankshaft, with double-arc helical gears mounted at both ends of the crankshaft to transmit power and counteract axial forces.

3. The power end and the fluid end are connected by 8 alloy steel tie rods. When removing the fluid end, the tie rods remain attached to the power end.

4. The connection between the plunger and the crosshead uses threaded connections, making disassembly and maintenance of the fluid end easy.

5. The fluid end allows for four different plunger sizes (3.75", 4", 4.5" and 5") with the same pump head to achieve various displacements and pressures for customer selection.
