APPR pumps

High pressure pumps with integrated energy recovery exchanger

APPR high-pressure pumps were designed by Aqua-Life partnership company.  APPR pumps can be used for sea or brackish water and are designed for applying in reverse osmosis systems. APPR pumps are the most advanced pumps in the world that contain an internal energy recovery device (2-in-1).

Thanks to the internal energy recovery device more than 60% of the driven energy comes from the high-pressure brine that passes through the pump and transfers energy to the plungers.

Benefits

The first pump with an integrated ERD. Most manufacturers recommend using separate energy recovery devices in order to reduce energy consumption. But in that case, the price grows up sufficiently and a new device demands space and additional fittings

Low operation cost. The pump provides uninterrupted operation without direct maintenance for at least 8000 hours

Ultra-low energy consumption. Thanks to ERD energy consumption are reduced more than two times if compared with equivalent high-pressure piston pumps

Absence of lubricants. All contacting surfaces are lubricated by the seawater flowing through them

High corrosion resistance. All metal parts are made of Duplex and Super Duplex steel that has extreme resistance to corrosion.  Non-metallic parts are made of PEEK polymer, which is also highly corrosion-resistant and wear-resistant

Compact size and quick installation. All APPR pumps are very compact design relatively to their flow rates and are connected directly to the motor using a coupling

Why APPR is so good?

The APPR pump contains an internal energy recovery device and therefore uses two energy sources:

A – the rotor receives rotation from the electric drive and the pistons move

B – movable hubs are put on the pistons and transfer to them the energy received from the high pressure return brine

All metal parts are made of duplex and superduplex steel, so the pump has extra resistance to corrosion in salt water condition

No oil is used for lubrication; all friction surfaces are lubricated by the saltwater passing through them

The integrated adjustable valve regulates outlet pressure, screwing on the valve increases the pressure and unscrewing the valve decreases it

Manufacturing process

Product range

High pressure pump with integrated energy recovery exchanger


Outlet rated pressure: 55 bar (785 psi)


Outlet maximum pressure: 70 bar (1000 psi)


Rotation speed: 1000 - 1700 rpm.


Flow at speed 1465 rpm: 3.3 m3/h (13 gpm)


Driving motor power at rated pressure: 4,0 kW


APPR pumps can be used for salt or brackish water and are designed for applying in reverse osmosis systems. APPR pumps are the most advanced pumps in the world that contain an internal energy recovery device, therefore APPR is both a high-pressure pump and an energy exchanger.

Thanks to the energy exchanger energy consumption are reduced more than two times if compare with analog high-pressure piston pumps.

All metal parts are made of Duplex and Super Duplex steel that has extreme resistance to corrosion.  Non-metallic parts are made of PEEK polymer, which is also highly corrosion-resistant and wear-resistant.

The pressure is regulated by an integrated adjustable valve, screwing of the valve increases the pressure and unscrewing of the valve decreases the pressure.
