Product Description

ZDG self-balancing multistage boiler feed pump

Brief introduction

ZDG self-balancing multistage boiler feed pump are suitable for pumping boiler feed water at a maximum temperature of 210°C. They represent a major advance in high lift multi-stage pump technology and are designed to meet the stringent demands of modern day boiler feed water methods. Sanchang Pump manufactures different pump models for effective operation under varying conditions.

Features

1. The pump units are robustly constructed to withstand the harshest factory environments, and incorporate modern hydraulic design principles.
2. Conventional balancing discs and the associated maintenance problems are completely excluded by fitment of opposing impellers on either side of the centre casing section which eliminate hydraulic thrust.
3. The units are maintenance free, thus pump stations can be fully automated, significantly reducing operational,maintenance and labour costs over the entire life of the pump.
4. Refurbishment cost of ZDG pumps units is significantly reduced due to the minimal axial and radial thrust of the rotating element.
5. The pump units are high effient and energy saving compared to traditional multistage pumps.
