Cost effective solution to extend your pump reliability

Type 5 S/S

What is the use of a BOA?

Installed on pumps that have oil sumps.
The BOA is installed into the pump housing drain plug underneath the pump housing/sump, to improve the running time of the bearings by monitoring the quality of the bearing oil and proportion of oil to water.
The BOA allows oil samples to be taken from the bearing housing/sump by opening the ball valve drain, giving insight to the quality of the oil.
Early detection of any oil contamination results in continued pump reliability.
Magnet is installed in the sight glass to attract metal particles that could potentially be contaminating the oil.
The BOA is easily removed when the pump is isolated and simply disassembled for cleaning. New O rings are fitted, to then be re-assembled and installed back onto the pump.
Type 7 is a shorter design for pumps where space is limited from the underside of pump bearing housing to the pump mounting base.

Type 7 S/S

“Our success started with an order from Exxon/Mobil Fawley Refinery UK, where we supplied 1200 units. We designed the Sight Glass Type 5 & 7 S/S, which has now been accepted in many refineries around the world.”

Oil Contamination

Image on the left: Filled with oil and water. Water is heavier than oil, therefore is seen at the bottom of the BOA, showing clear water contamination.
Image on the right: Demonstrates the use of the magnet attracting any metal particles that is contaminating the oil in the sump.
