Product Overview

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

Performance advantages

Double-suctionimpeller to reduce axial force to a minimum; CAD hydraulic model to optimizethe best design, good performance; addition of a prototype impeller,it can alsouse modified impeller to adapt to different working conditions, improveefficiency .

Accordingto the forces condition, pump with double volute form to reduce the radialforce, to be small bearing force and long life; easy installation, automaticcalibration of the pump cover; relative position of in and out of the pipelineof the motor and the pump may change according to the user site requirements; pumpinlet without swirl, smooth running, low loss; through precision casting, pumpcasing and impeller surface to be very smoothly, with significant anti-cavitationperformance and high efficiency.

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

Crudeshaft with advantage of rigid, smooth operation and new structure; rotorreversals for short-term without damage, and easy commutation; completelysealed shaft, without touching the liquid, non-corrosive thread; standard spareparts to ensure the assembly size,replace without adjustments.

BURGMANNmechanical 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; injectionwadding with online maintenance functions, maintenance without stoping to avoidcostly shutdowns loss, low friction power, no leaks.

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