SOW horizontal split-casing double-suction pump

Urban water supply and drainage, urban water supply, central heating systems and drainage,agricultural irrigation, drainage and various water projects.
Product description

Product Overview

SOW series horizontal single-stage split-casing double-suction centrifugal pump is the latest generation of split-casing double-suction pump,with notable features of perfect spectrum, good model and outstanding performance, innovative and reliable structure, easy maintenance and long life. Our current SOW pump has 46 models, 390 basic specifications. By using the prime impeller and modified impeller and cutting type, full of broad-based spectrum, high efficiency and performance range in the type spectrum, appropriately to meet the user needs at any point in the work flow and head. By carefully manufactured and perfect quality control, this product has reached domestic leading level. This series of pumps meet ISO2548C, GB3216C, GB/T5657 standards.

Performance advantages

Double-suction impeller to reduce axial force to a minimum; CAD hydraulic model to optimize the best design, good performance; addition of a prototype impeller,it can also use modified impeller to adapt to different working conditions, improve efficiency .

According to the forces condition, pump with double volute form to reduce the radial force, to be small bearing force and long life; easy installation, automatic calibration of the pump cover; relative position of in and out of the pipeline of the motor and the pump may change according to the user site requirements; pump inlet without swirl, smooth running, low loss; through precision casting, pump casing and impeller surface to be very smoothly, with significant anti-cavitation performance and high efficiency.

SKF and NSK grease lubricated bearings, convenient maintenance, bigger size, long life; tail bearing for bush bearings plus key installation, fixed and reliable, easy disassembly.

Crude shaft with advantage of rigid, smooth operation and new structure; rotor reversals for short-term without damage, and easy commutation; completely sealed shaft, without touching the liquid, non-corrosive thread; standard spare parts to ensure the assembly size,replace without adjustments.

BURGMANN mechanical seal or packing seal; quality mechanical seal without leakage, mechanical seal sleeve of stainless steel to avoid corrosion, easy maintenance; meet the environmental requirements of the non-asbestos wadding; injection wadding with online maintenance functions, maintenance without stoping to avoid costly shutdowns loss, low friction power, no leaks.

Base to be welding steel chassis can be equipped with high impact resistance, good toughness, lightweight and durable, according to requirements at site.


This product is widely used in urban water supply and drainage, urban water supply, central heating systems and drainage, iron and steel metallurgy companies, oil refineries, paper mills, oil, power plant, airport construction, chemical plants, textile mills, sugar mills, chemical plants, power plants and drainage, plant mines consumer drainage systems, air conditioning systems of water supply, agricultural irrigation, drainage and various water projects.
