ROTARY GEAR PUMP (HRC)
Harivallabh Roto Industries offers the Rotary Gear Pump Model “HRC” (Rotary Gear Pump) Which Is a positive Displacement Rotary Gear Pump. Model “HRC” has simple Two Pieces Graded Cast Iron Construction Which Is a Single Helical Modified Profile En8 Gear Shrink Fitted On En 19 Hardened And Grind Finished Shaft As Gear Firmly Supported 4 Nos. Of Self-lubricated Du Bush Bearing Which Ensures Smooth Running. Rotary Gear Pumps Can Be Run In Either Direction With a Change In Inlet-outlet Port Position. The Relief Valve Operations Can Be Reversed By Simply Changing The Relief Valve Parts On the Opposite Side.<br><br>
The Suction And Delivery Connections Are Available In 1/2″ To 3″ Sizes. Rotary Gear Pumps Can Be Operated Up To Pressure Of 10 Kg/cm2 With 20 Lpm To 500 Lpm Flow Capacity. Rotary Gear Pumps Are Designed To Run At 1440 Rpm Viscosity Up To 1,00,000 Ssu And Maximum Temperature Up To 200oc. It Is Desirable To Reduce Speed For Size Above 1/2″ Performance At Low Speed Is Always Advantageous As It Improves Efficiency, Reduce Noise Level And Enhances Operational Life. The Capacity Will Reduce In Proportion To The Speed.
