The South African Bureau of Standards (SABS) conducted a successful 4-hour demonstration test on one of the country’s largest centrifugal diesel pump systems. The test was conducted today, in Pretoria at the SABS’ pump test facility. The pump weighs 32 000 kg, has the ability to pump water at a rate of 2 800 m3/h (cubic meters per hour) and is used under emergency conditions for the suppression of Hydrofluoric Acid vapour.
The performance test forms part of a customer process to demonstrate the functional capability of a diesel and pump combination to its end user.
The SABS pump test facility can test a number of rotodynamic pumps which includes centrifugal, mixed flow or axial pumps. The tests are conducted according to the specifications referenced in the South African National Standard (SANS) 9906-2016.
“These large pumps with their huge capacity are required in the mining, petro-chemicals and power sectors when large volumes of water are needed to be pumped. Using a diesel engine ensures that they can be used when an emergency situation occurs, such as fire or vapour release. The SABS has conducted many tests at this facility since 1978 and this is the largest system in recent years.” says Johan Louw, Executive of SABS Laboratory Services.
The SABS test facility has a water tank and sump that is 5 meters deep and contains 735 000 litres of water.
“The SABS is the ideal choice for testing and certifying of rotodynamic pumps. Our test equipment allows us to test submersible pump systems as well. Some of the regular tests that we conduct include pressure, flow and torque tests against SANS 9906: 2016,” says Erich Seeger, Senior Manager: SABS Laboratory Services.
SABS has a large 300m2 laboratory which is capable of configuring various sizes of equipment and pipe systems.
Line limits on the water flow include:
- 80 mm line up to 114 m³/h
- 150 mm line up to 350 m³/h
- 250 mm line up to 850 m³/h
- 400 mm line up to 2000 m³/h
- 700 mm line up to 8000 m³/h
The test facility also has the following valves available:
- 150 mm actuated valve
- 200 mm manual valve
- 250 mm actuated valve
- 300 mm manual valve
- 400 mm butterfly manual/actuated valve
“Most of the high volume pumps are manufactured by international companies and are then assembled in South Africa. Having a South African test facility that offers independent test facilities for the benefit of local manufacturers and importers. Since November 2018 the SABS has enabled customer specific requirements (CSR) testing which will also support the local manufacturers’ development and export objectives. The SABS is recognised for their independent and reputable test facility and has plans for further enhancing its capabilities’, says Seeger.
