Valves

Our goal is to offer valves in seawater resistant materials to be used with the APP pumps and pump systems.

The VCM valves are mainly used to prevent the pumps from spinning backwards - which, however, is not harmful to the pumps, but the low-pressure feed line will be protected against high pressure in case of sudden power cuts.

Accessories

Danfoss A/S RO Solutions can provide a range of accessories enabling system builder to build their own pump systems with high quality components approved and tested by Danfoss.

Hoses with 1½” Victaulic connections can be offered in two lengths to be mounted on the APP pump discharge providing flexibility in respect of connecting the pumps to the high-pressure side.
If another hose length is requested, Danfoss can provide standard pipes in Duplex for 1” high-pressure hoses.

Bell housing for all standard B5 electric motors incl. couplings are off-the-shelf-items.

Pump Systems

Although the biggest APP pump “only” supplies 10,2 m3/h, it is possible to increase the feed flow to the membrane.
Danfoss A/S RO Solutions can provide a variety of pump systems on frames in all sizes – up to 40 m3/h feed flow …. and we are still competitive on price.

Special pump systems for hazardous areas are supplied regularly for offshore applications with all the necessary approvals.

RO Solutions



Danfoss A/S RO Solutions is a new product line based on well proven technology introduced in 2002 with a range of high pressure pumps in duplex and super duplex materials designed for pumping low viscosity and corrosive media like high-saline seawater.

We provide pumps and pump systems in the range of 0.2 to 40 m3/h running at efficiencies up to 95% with extremely long service lives. Since the introduction of the pumps, several records have been made reducing the energy consumption of water makers.

In addition to the basic pump function of the pumps they are often used for energy recovery when reversing with the brine as the energy source.
