Internal gear pumps
The size of a pump is not an indicator of its quality and performance. It comes down to the heart of the motor - the gear operation. A pump demonstrates its qualities in low-noise operation even at high compression and allows for many hours of operation free of maintenance.
SP manufactures pumps in with a performance range of 0.13 - 0.55 cm³/U for greasy fluids. The sealing materials are then adapted for every medium.
It should be noted in particular that the achievable vacuum is up to 8m. Multiple geometries of casings are possible here. Additionally, the casings are received in a gas nitrocarburizing version.
