Overview

Advantage 1: Stability and reliability.

The DPE pump is a two-stage structure designed for low flow, medium to high head, and small NPSHA operating conditions, ensuring NPSHR ≤ 1.5m@3000rpm ;
The radial load of DPE pump can be minimized at all operating points, and the unit has high reliability. The design fully considers the operating conditions of
extreme operating conditions to ensure the continuous operation of petrochemical process equipment; Various forms of sealing and flushing cooling schemes
can be configured, suitable for various complex working conditions and with a wide range of applications.

Advantage 2: Economy.

It can replace some high-speed pumps, plunger pumps, multi-stage pumps, and rotary casing pumps, with simple structure, convenient maintenance, high
reliability, lower investment and maintenance costs, small installation space, and can be suitable for harsh working conditions such as containing particles.
