The D4 pumps are used for a number of different fluids:
Lube oil, hydraulic oil, diesel & fuel oil and any non-aggressive fluid with sufficient lubricating properties.

Typical applications are:
- Fuel oil burner pumps for steam boilers (at paper mills, marine boilers, power plants)
- Circulation of fuel oil
- Lubrication oil systems
- Power hydraulic pumps for milling plants
- Filling pumps for hydraulic presses
- Seal oil pumps for compressors

The pump is designed to be flange mounted to its electrical motor via a connection frame and a flexible shaft coupling. By the angle bracket, the pump may be mounted horizontally or vertically.

As standard, counter flanges are included.
