New titanium pump helps keep the sewage flowing

The TM pump series is suitable for applications where corrosion is an issue.  The stator housing is titanium whilst the pump casing, stand and motor cap components are all manufactured from FRP resin moulded material.  Although the range was originally designed for seawater, it has proved to be ideal for highly corrosive chemical applications in food and chemical plants. 

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.

The oil chamber incorporates a patented oil lifter that ensures lubrication even if the oil level in the chamber drops. This increases the time between routine pump maintenance.

The TM series is also available with floats for automatic operation. The float height can be pre-set and the automatic pumps offer a low cost control solution. Installation is simple as there is no external control panel or additional wiring required.
