A three-point base-mounted unit is a fixed version of the Börger rotary lobe pump on a stable triangular frame. It is used at industrial sites where the pump must stay in a permanent fixed position: on process lines, in transfer stations and as part of automated metering and batching systems. An alternative to mobile units where work is done at a single point.
Design of the three-point base
A frame with three feet provides stability on uneven industrial floors without elaborate foundation work. Each foot is height-adjustable, which allows the pump to be levelled precisely even on a sloping floor. Fixing to the floor is by anchors. The design is more compact than a linear frame and leaves free space around the pump for servicing.
Performance data
- Capacity — from 50 to 300 m³/h depending on the pump size
- Discharge pressure — up to 12 bar
- Self-priming — up to 9 m
- Pumping of liquids with solids up to 100 mm
- Handling of media with viscosity up to 1,000,000 mPa·s
- Drive — electric motor or geared motor with variable-frequency control
Where it is used
On oilfields — as part of crude oil treatment systems and process liquid transfer. In municipal services — at sewage pumping stations. In the food industry — on filling lines for viscous products between tanks. In the chemical industry — for transferring reagents and emulsions between reactors. In agriculture — for feeding biogas plants.
Advantages of the fixed version
Compared with flange-mounted installations, a pump on a three-point base is simpler to install: no flat foundation preparation and no linear guides are needed. Compared with a mobile unit it takes up less space and does not require an operator to be present at all times. MIP technology is retained: repairs are carried out in place without disconnecting the pipework.
Selection and configuration
The choice of pump for the unit depends on the nature of the medium, the required capacity and the duty cycle (continuous or intermittent). For pumping with a high solids content we recommend an upstream Börger grinder. The operating principle of the pump end — in the article on Börger rotary lobe pumps.
