Gear Pump + Relief Valve (PR3)

The PR3 series gear pump with a relief valve combines the pumping action of a gear pump with a safety mechanism provided by the relief valve. This setup ensures a consistent flow of fluid while preventing damage to the pump and the overall system by controlling excessive pressure. This type of pump is commonly used in applications where precise and constant fluid transfer is required, and where pressure regulation is essential to maintaining the integrity of the equipment and the safety of the process. Displacement: 2 ~ 35 c.c. / rev. Max. Pressure: 250 kg/cm2 (3500 psi) Flange: SAE 2-bolt, DIN 4-bolt, European 4-bolt
