Description
The pumps are compact in design and are available in single or three phase motor drive. They range from pumps capable of 240l/m flow right up to 350 l/m. Heads vary from 9m to 15m.The pump used in the Douglas Park station (south west of Sydney) needs sump pit is a Tsurumi 50TM2.4S single phase submersible with flows to 290/m and a max head of 12m.
The TM series features a vortex impeller made from glass-fibre reinforced resin. An anti-wicking cable gland prevents water incursion due to capillary wicking should the power cable be damaged or the end submerged.A dual silicon carbide mechanical seal is protected in an oil chamber so neither seal face contacts the pumped liquid. This eliminates abrasion and facilitates cooling and lubrication of the seal faces.
