IS ISR Centrifugal Water Pump
IS ISR are single-stage single-suction centrifugal pumps for clean water and liquids with similar physicochemical properties. IS serves medium up to 80°C; ISR with high-temperature construction works up to 150°C for hot water service. The pump consists of casing working chamber, rotor (impeller, shaft, rolling bearings) and bracket bearing assembly. Axial thrust is balanced via impeller wear rings and balance holes; shaft is protected by shaft sleeve with O-ring, and shaft sealing adopts packing structure. The pump connects to motor via extended flexible coupling and rotates clockwise from drive end.
Product details
Product Features
1.ISR adopts centerline-supported casing to relieve thermal stress under high temperature; cooling chambers are arranged on bracket, cover and seal housing for water/air cooling.
2.Bearings adopt thin-oil lubrication with rated service life of around 25,000 hours for higher load capacity.
3.Shaft seal is available in packing seal or mechanical seal options.
Main Application
1.IS: industrial & municipal water supply/drainage, agricultural irrigation and drainage.
2.ISR: boiler feedwater, hot water circulating & HVAC systems. Widely applied in power, metallurgy, textile, chemical, printing & dyeing, ceramic, rubber and heating industries.

S SH Split Case Pump
S/SH is horizontal single-stage double-suction split case centrifugal pump for clean water or medium with water-like properties; permissible medium temperature ≤80℃. Split casing enables overhaul without detaching inlet/outlet piping or motor; standard rotation is counterclockwise viewed from coupling side.
D DG Multistage Pump
D & DG are horizontal segmental single-suction multistage centrifugal pumps for clean water (impurity ≤1%, particle ≤0.1mm) and analogous liquids. Max medium temp: D ≤80℃, standard DG ≤105℃, customized DG ≤120℃. Standard D has horizontal suction & vertical upward discharge; oilfield-type D and all DG feature vertical upward inlet & outlet. Fitted with packing seal: D uses internal pump fluid for seal water while DG adopts external water supply, driven by motor via elastic coupling.
