What is a DIY Pumping Station?

Pumping Stations are an assembly of pump and fittings destined to circulate heat transfer fluid between Heat Source (Vacuum Tube Solar Collector) and a Heat Sink (Solar thermal Storage tank). Most Factory Pre-assembled pumping stations are expensive to buy and offer little or low pumping head (less than 18 ft in total head). For Installation requiring multiple solar panel with longer distances between heat source and heat sink, client is forced to either buy multiple solar pumping stations or split his solar installation into a set of parallel independent ones. In both cases, project cost increases exponentially.

Our DIY Pumping Station offer more pumping head without the frills of factory built pumping stations that customers never make use of. Our DIY Pumping Stations are shipped in pieces (completely Knocked down) and must be assembled by installer.

This Pumping Station offers 1.5 times the head of CALEFFI COMMERCIAL SOLAR PUMP STATION NA255160 at almost half the price.
