HG Series pumps are self priming, foot mounting type positive displacement rotary gear pumps. Pumps have a simple two piece cast iron construction which is a single helical, modified profile, carton steel gear shrink, fitted on alloy steel hardened and grind finished shaft. These pumps can be run in either direction with change in inlet-outlet port position. The suction and delivery connections are available in 1/4″ to 3″ sizes. These pumps can be operated up to pressures of 10 kg/cm² with 5 LPM to 500 LPM flow capacity. Pumps are designed to run at 1440 RPM up to viscosity of 50,000 SSU and maximum temperature up to 200ºC. It is desirable to reduce speed for sizes above 1½”. Performance at low speed is always advantageous as it improves efficiency, reduces noise level and enhances operational life.
