The document describes the Screw pumps – PE4 series with relief valve, suitable for hydraulic oils and lubricating oils. It has an adjustable relief valve and is suitable for industrial general-purpose low-pressure applications. The product can provide a delivery flow of 10 to 550 l/min and a maximum allowable continuous delivery pressure of 40 bar. The product is suitable for a temperature range of 0 to 120 °C and a driving speed of 750 to 3600 rpm. The recommended filtration is 60 microns, and the direction of rotation is clockwise. Different relief valve pressure settings can be achieved by adjusting the valve.
This document provides technical specifications for the SEIM PE4 series of screw pumps, designed for industrial general-purpose applications involving hydraulic and lubricating oils. The pumps feature aluminum alloy casings and are available with standard relief valve settings of 7, 16, or 40 bar.
Key functional characteristics include a delivery flow range of 10 to 550 l/min and an admissible delivery pressure up to 40 bar. The pumps operate with a driving speed between 750 and 3600 rpm and are suitable for fluids with a kinematic viscosity of 10 to 400 cSt.
