GEP’s RCD pumping systems have been built using the high-quality selfpriming GEP RC pumps, equipped with built-in thermal protection and GEP’s DPA pump control. It is recommended to extend these sets with a pressure vessel from GEP. These hydrofore sets are suitable for pressure increase and rainwater use in industry and utilities, or can be used in all places where the water pressure needs to be increased.

The IRM®-3 & 5 Watermanager is a plug-in, compact installation for rainwater use in single-family homes. The break tank for drinking water supply is in accordance with EN1717 type AB. Content 7 liters. The IRM®-3 & 5 Water Manager has a self-priming centrifugal pump (RC-3 or RC-5) with automatic pressure control. The motor-controlled ball valve provides for the switch between rainwater and drinking water operation.
Control provides an automatic drinking water refreshment system that regularly switches the system to drinking water. For example, the contents of the break tank are regularly updated and prevent the tap water in the drinking water pipe from being idle for too long. In the absence of rainwater, the system automatically switches to drinking water by means of the float with a 20 meter cable length. The IRM®-3 & 5 Watermanager
is equipped with a sound-proof EPP housing. The IRM®-3 & 5 Water Manager is suitable for wall mounting. The device is KIWA, Belgaqua and DVGW certified. -
The IRM®-3S & 5S Water Manager is a complete rainwater system in combination with a pressure immersion pump in the rainwater tank for the use of rainwater in single-family homes. The break tank for drinking water supply is in accordance with EN1717 type AB. content 7 liters The Water Manager is supplied with a pressure immersion pump (combi-press 5-30 or combipers 5-60) with 2 connections on the suction side. The
pump is supplied with a floating suction hose for mounting on the suction side. The other suction side is used to connect the drinking water supply from the IRM®-S Water Manager. The motor-controlled ball valve provides the supply of drinking water to the pressure submersible pump. In the absence of rainwater, the system automatically switches to drinking water by means of the float with a 20 meter cable length. The control also provides for automatic drinking water refreshment of the break tank with long-term use of rainwater. The Watermanager is provided with a sound-proof EPP housing. The IRM®-3S & 5S Water Manager is suitable for wall mounting. Device is KIWA, Belgaqua and DVGW certified. -
The IRM®-9 Watermanager is a water management system with breaktank and built-in dual multi-stage submersible pumping system. The IRM®-control unit operates according to IOT and monitors the water levels in the breaktank and rainwater tank. The control unit also provides cascade control and operating hours control for the pumps. The direction of the supply and return pipes can be flexibly mounted. In case of lack of rainwater, system failure or manual operation, the system switches over to potable water, via a Type AB interruption, in accordance with EN1717. Belgaqua and KIWA certification is ongoing (02-2025) The drinking water connection is equipped with a water shock absorber for protection of the supply pipes and a stagnation safety device that automatically refreshes the water in the appliance. The control panel of the IRM®-9 Watermanager shows the operating status, pump status, IOT connection status and faults. Optionally there is a potential free contact, which enables connection to home automation and building management systems.

The IRM®-Hybrid system control system automatically replenishes the hybrid tank with rainwater from the large rainwater tank. In the absence of rainwater, the hybrid tank switches to drinking water. The control can also be switched manually to drinking water. Optionally, the rainwater tank can also be equipped with a pressure sensor so that the current water level can also be displayed by the GEP Hybrid control system.
The display of the hybrid control is done via an LCD display. The system is continuously monitored and any faults are reported by the control, not only via the LCD display, but also via an acoustic signal and a potential-free contact. In addition, the control system provides a stagnation protection for the supplying drinking water line and a data log of the various operating hours. There is also the option to connect a backflow protection. When returning from the sewer to the rainwater tank the control will report this and automatically switch to drinking water. -
