Gerotor pumps, product series 143 Fundamentals General use Delivery rates and characteristic curves SKF gerotor pump units of product series 143 are used in circulating-oil and total-loss lubrication systems in a flow rate range of 0.85 to 50 l/min. The standard permissible ambient temperature is between 0 and +40 °C. Higher ambient temperatures are possible, though they lead to a reduction in motor performance and thus the delivery rate. The permissible temperature of the pumped medium is between 0 and +80°C. The gerotor pumps are available in NBR and FKM designs. SKF gerotor pump units feed...

Gerotor pumps, product series 143 Fundamentals Design (→ Figure 1) SKF gerotor pump units of product series 143 have a constant displacement volume and one delivery circuit. The annular-toothed feeding element, also referred to as the gerotor, is equipped with a cycloid contour, which creates a large tooth meshing length. This yields a low volumetric flow pulsation and thus very smooth running, low noise production, and good suction characteristics. SKF gerotor pumps consist primarily of pump housing (1), the shaft (2), the displacement elements toothed rotor (3) and annular gear (4), and the...
