The OM(A)4 pumps are light, compact, have energy efficient motors and integral anti-airlock valves. Available as manual or with a tube type float switch, for automatic operation in areas with limited space or where precise level control is required. Liquid paraffin is used for the lubrication oil, which enables use in food processing and aquaculture. They are not recommended for ponds or water features.
Users of 230 volts have the option to select from two versions: the “domestic” is supplied with a hose tail, a hose clip (for fitting to flexible discharge hose) and a 3 pin plug (fitted with a 5 amp fuse).
The “industrial” has a female BSP outlet (for fitting rigid waste pipe) but a plug is not supplied. 110volt pumps are supplied as “industrial”.
