Centrifugal pumps transfer liquid by converting rotational energy from an impeller into pressure. IS/ISW series: flow 1.5–1600 m³/h, head 2–125 m, power 0.18–250 kW, temperature ≤80°C. Best for water and low-viscosity process liquids requiring continuous non-pulsating flow. For viscosity above 150 cSt, switch to a gear or screw pump.

What data is needed for a centrifugal pump quotation?
Flow rate (m³/h), total head (m) or discharge pressure, liquid name and temperature, specific gravity and viscosity, available NPSH, motor voltage and IP class, and installation orientation.
IS series horizontal centrifugal pump consists of a pump casing, pump cover, impeller, shaft, seal ring, shaft sleeve, and bearing assembly. When liquid is subjected to centrifugal force, the volume of liquid at the impeller center gradually decreases, creating suction at the pump inlet that draws fluid into the pump.

What is a centrifugal pump used for?
Centrifugal pumps use a rotating impeller to transfer liquids continuously and are widely used for water, wastewater and process-fluid circulation.
What information is needed to select a centrifugal pump?
Provide flow rate, total head or pressure, liquid name, temperature, specific gravity, viscosity, available NPSH, motor power supply and installation requirements.
Can a centrifugal pump handle high-viscosity liquids?
Centrifugal pump efficiency decreases as viscosity rises. For many applications above roughly 150–200 cSt, a positive-displacement gear or screw pump should be evaluated.
