Pump Features: 1. European Standard BS EN733/DIN24255 of performance and dimensions 2. Back-pull-out design, without having to disturb pump body and pipelines when servicing. 3. All the models only use 3 kinds of pump shafts and bearing cover, make parts exchangeable. 4. Impeller is optimized designed, inlet is enlarged, no whirlpool, deduct the water pump NPSH efficiently, which makes pump work stable with little noise. 5. Casing and casing cover use wearing neck ring structure, which makes pump easy to maintain, makes parts work longer. The replaceable seal ring, makes pump work efficiently in a long time Pump Construction : 1. Non-self-priming, single stage, single suction, horizontal, axial suction and radical discharge, pump body is fixed by base. 2. Use bearing cradle, which can orientate bearing, prevent from radical vibration, improve the rigidity of rotary part. 3. Compacted shaft, use deep grove grease lubricated roller bearing 4. Connect pump and motor with semi-flexible coupling 5. Use standard wearable mechanical seal. 6. TEFC motor, size complies to IEC standard, installation type B3.
