In addition to the standard end-suction DIN 24255 Baker Pumps supplied for the primary heating water, we also provided a cost-effective solution for the spa and pool heating circuits. For these circuits we offered the Southern Cross DPV range of multi-stage in-line pumps. All wetted rotating components are stainless steel with a tungsten carbide hard faced mechanical seal. They are rated to 25 Bar and come complete with companion flanges with BSP female-threaded connections. Another major benefit of these pumps is their simplicity and economy for repairs. This is brought about by the reduced axial thrust achieved by the application of in-built thrust bearings being located in the pump rather than in the motor. This feature allows a standard metric frame motor to be used, thereby creating a simple, more economical means of motor replacement - a distinct advantage over other multi-stage pumps which have their own unique motors fitted. In summary, we provided: • The pumps were supplied on top hat section bases with RIS mounts supplied loose. • For the 25-metre pool the DPV -10-2 (2.19 litres/sec @ 180mps) was chosen. • For the 50-metre pool, we selected the DPV 18-2 (5.06 litres/sec @ 150kpa) while the spa pump was the DPU4-26T (0.97 litres/sec @ 150kpa). • A fourth pump (not pictured) is the leisure pool heating pump which was the DPU 18-1 (4.34 litres/head @105kpa).
