Description Performance parameters

Product Overview

KDY type horizontal multi-stage horizontal center-open centrifugal oil pump implements API610 11th edition and ISO13709 "centrifugal pump for oil, heavy chemical and natural gas industry" standard, which is a heavy-duty, horizontal axially split, two-end supported, quasi-centerline mounted centrifugal pump, suitable for heavy-duty occasions.

The series of pumps are simple in structure, easy to maintain and have high reliability. The entire rotor can be replaced within 8 hours, and maintenance and replacement parts do not require moving the inlet and outlet pipes and motor. The series pump only needs to be opened every four years for internal inspection and overhaul.

With its unique high efficiency and energy saving, reliability, high temperature and high pressure resistance, this series of pumps has become a new generation of heavy duty process pumps, which can be widely used in various industrial fields.
