Salamander RCM1 Automatic Negative Head Kit

Salamander RCM1 Automatic Negative Head Kit for Positive Head Shower Pumps.

This product will convert a positive head pump to negative head if the pump is 3.0 bar or more. Two RCM units are required for twin pumps.

Negative head systems exist where no natural flow of water goes to the outlet because either the outlet or the pipework to the outlet are above the height of the base of  the cold water cistern. Most instances of negative head systems occur in loft conversions or where the cold water cistern sits on the joists in the loft. If the distance between the bottom of the cold water cistern and the highest point in the system after the pump is 2 feet (610mm) or less, it is also possible that a universal pump will be required. Salamander’s universal range of pumps activate the pump automatically even where no natural flow exists.

CT FORCE pumps suitable for negative head operation are CT FORCE 15 TU, 20 TU, 20 SU, 30 TU and 30 SU.
