BMG’s Steimel gear pumps for harsh applications

BMG’s range of Steimel lubricant and feed gear pumps – the SF series – is used mainly on oil lube systems in mines, steel works, power stations and general industry.

“SF heavy duty pumps, which offer pulsation-free pumping delivery, are designed to pump any grade of lube oil, including high viscosity oils. These pumps are particularly suitable for transporting media with some minimal lubricity, is chemically compatible and does not contain solids,” says Joe Pinheiro, BMG’s national product manager, pumps. “SF gear pumps are used as circulation pumps in oil lube systems, kidney systems and for transferring (off-loading or dispensing) of oils.

“These compact pumps are easy to assemble and detach. The standard design is supplied with a clockwise rotation, which is easily altered to anti-clockwise, by rotating the end cover plate by 180˚. The direction of delivery flow will change at the same time. An optional feature is an adjustable pressure relief valve built in the housing, for short term protection against pressure spikes.

Optimum integration, with minimal tolerances of the pinions and gear wheels results in quiet, smooth running. The use of gear wheels with 12 teeth reduces delivery flow pulsation and minimises noise during operation. Shaft journals are mounted in composite bearing bushes which ensures continuous duty and extended service life. All pumps sizes can be equipped with an anti-friction bearing at the driving end, to accommodate radial and axial forces.

Standard pumps have a maximum rotational speed of 1 800 rpm for a maximum viscosity up to 380 cst and a differential pressure up to 25 bar. The maximum permissible rotational speed depends on the viscosity or lubricity of the medium. The higher the oil viscosity, the lower the speed. These pumps can handle media with a viscosity range from 5 to 50 000 cst and can withstand a temperature range between -40 ˚C and +250 ˚C.

Also in the Steimel range are SF ATEX gear pumps, which provide a high degree of safety in potentially explosive environments.

Type SF M feed pumps, with a magnetic coupling, are hermetically sealed and can operate safely in applications at elevated temperatures and also withstand media that this difficult to seal.

BMG also supplies the Steimel feed pump T series on request. These rotary gear pumps, which are designed to transport almost all media, can be used to maximum rotational speeds of 1 500 rpm, at pressures up to 16 bar. This range is suitable for food processing, paint production and for handling printing inks, bitumen and resins.

Steimel Model B lubricant and feed pumps are designed to efficiently handle highly fluid media, like waste oils, greases, hardening and hydraulic oils, resins, lubricating greases and oils, as well as turbine and thermal oils.

These pumps have a permissible excess pressure up to 50 bar, a viscosity range up to 5000 cP and a displacement from 2 to 75 cm³/rotation.

BMG offers a technical advisory service to ensure selection of the most suitable pump size for every specific application. The company supports this range with a spares facility and 24 hour maintenance service through more than 130 BMG branches and a wide distribution network in South Africa and across borders into Swaziland, Zambia, Botswana, Mozambique, Namibia and Tanzania.
