The 504 submersible pump is a direct replacement for the Calpeda 404 pump as supplied with domestic rainwater harvesting systems (model DPX or PRO) These systems can be easily identified by the wall mounted control panels. The DPX or PRO's were supplied with either black plastic covers over a metal backboard or with a dark blue plastic housing (both back and front cover). These systems are also usually operated by another small box, called the Freerain management and these also display the water level in the tank.
Please note, the standard pump supplied with these systems is a 304 pump. The 504 (formally 404) was supplied to applications with a larger demand than a standard residential building.
These pumps are supplied with a 15-metre cable from the manufacturer. We have also provided two other cable lengths for you to choose. But please note that the 25 and 35-metre options are two lengths of cable that we have joined in our factory and are joined using an IP68 junction connector.
