3ZB-265 triplex plunger pump

1. 3ZB-265 horizontal single acting triplex plunger pump
2. widely used for cementing , fracturing and circulating operations.

Brevity Introduction
300-type plunger pump is a single acting triplex plunger pump, which is of reciprocating type,positive displacement,and horizontal type. Its
maximum
rated braking power is 265kW (350hp). It is used for oil well
operation intermittently, such as cementing, acid treatment, fracturing,
and pumping water, etc.
The plunger pump mainly consists of a power end and a fluid end.
The
diameter of plunger can be chosen between 3-3/4”~5" so as to meet the
requirement of customers for different pressure and displacement. The
following requirements must be paid attention on when choosing working
condition.
