Project Description

ZD02

Sproull® ZD Self-priming Sewage Pump is designed for delivering large solid particles and long fiber impurities, with advantages of simple structure, good self-priming performance, high sewage capacity, high efficiency, energy saving, convenient usage and maintenance, It is widely used in municipal sewage project, river and pond breeding, light industry, paper making, weaving, foodstuff, chemical industry, power industry, fibrin, chemical medium, slurries and mixed suspension etc.

Working Condition:

Capacity: 2-650m³/h
Head: 3.5-150m
Working pressure:<1.6Mpa
Working Temperature:-50 – +200℃
Materials:304,316L,2507 Stainless steel,Steel Lining Teflon.

Design features:

• The pump is with self-priming performance, It don’t need any bottom valve.
•  Electric motor and diesel engine driven for options.
• The total weight of impurities in the medium can not exceed 15% of the total media weight.
• Medium specific weight not more than 1240kg/m³.
• The unique structure of open impeller makes sure the free pass of solids in sewage with max size of 60% of outlet DN and fiber 150% of impeller diameter.
• The self priming sewage pump is widely applicable for the lines of urban diacharge projects, light industry, papermaking, textile, foodstuff, chemicals, electric power, petroleum, mines, aquiculture and so on.

Sproull® ZD Self-priming Sewage Pump is applicable to urban environmental protection, construction, fire protection, chemical industry, pharmacy, dye,printing and dyeing, brewing, electric power, ferry, paper making,industrial and mining washing, equipment cooling, etc.
