TANK FARM
Tank farms store fuels and can act as strategic oil reserves. Usually, the majority of tanks store products like petrol, heating or heavy oil and various chemicals (temporarily). The pumps used must have particularly good suction properties to guarantee that tanks and lorries are emptied completely.
Drainage pump
Petrol and middle distillate make up a large transport range. Pumps must not only be efficient, have a long life span and be powerful; they must also have a particularly large flow rate range. At a flow rate of 78 m³/h one tank wagon is connected to the suction line; at 380 m³/h several tank wagons are connected to the suction line. This option is common practice due to the time savings, especially in larger tank terminals.

| Temperature range: | -10-30 °C |
| Viscosity: | 0,8-10 mPas |
| Flow rate: | 78-380 m³/h |
| Suction pressure: | -0,5 bar |
| Differential pressure: | 6,0 bar |
Mobile residual pump drainage pump
In the large sector of petrol, middle distillate, petroleum and water transport, both drainage pumps and mobile residual pumps are used. Due to the gas/liquid mix inside the tanks, the tanks must be designed for ATEX Zone 1. Good suction properties during dry suction are particularly necessary.

Acceptance and transfer pump
Fatty alcohols, which are used as the basis for many creams and salves, are made from petroleum. A fully reversible pump is required to transport them. Liquids are placed in going one direction and come out again in the other. Screw pumps are perfectly suited as acceptance and transfer pumps.
