When there’s not enough space for dewatering you need a Tsurumi pump

When space is tight in dewatering applications you need a compact multipurpose pump from Tsurumi.

Dewatering pumps are seldom the focus for large manufacturers, but are among the stars of many job sites. Small dewatering pumps such as the LB series from Tsurumi are sold in large numbers worldwide. These pumps help when large amounts of water needs to be removed –  and are  used thousands of times every day around the globe.

Fits small pipes

Secured by rope or chain, an LB can still be used where pumps of other calibres are prohibited: in narrow pipes, small tanks, deep pits, rugged debris fields, and generally in remote locations that are difficult to reach with larger equipment. In short, virtually anywhere.

To achieve this, the manufacturer chose a fully symmetrical design with no protruding parts. Lowering to uncertain depths is therefore possible without any real risk of snagging. With a diameter of only 187 mm, the pump’s round cross-section even fits into the smaller filter pipes. Those who choose the version with a water level sensor only have to add a few millimetres. The pump then controls itself automatically, switching on or off depending on the water level. Because the Germany based company relies on electrodes instead of mechanics, technical susceptibility is minimal.

22 years of experience

The LB processes water with dirt particles up to 6 mm in size straight through the housing. This way, the motor is optimally cooled. The models in the series pump 225 to 440 litres per minute and pump up to a maximum of 17.5 metres. The smallest model weighs around 10 kg dry, the largest around three times that. The motor comes in different power ratings with a maximum of 1.5 kW. Depths of up to 25 m are possible.

The pump works horizontally or vertically and is designed to be extremely wear-resistant. Tsurumi’s oil distributor, a clever construction that ensures reliable circulating oil lubrication, is one of the reasons for this. Also, each electrical conductor is encapsulated in synthetic resin, which provide hermetic protection against creeping water damage. The manufacturer declares the pump to be safe to run dry. This means that even the smallest model can run unattended. Resistant materials are used both inside and out. Some parts are even made of silicon carbide, which is almost as hard as diamond. In this respect, the LB is a real jewel among multipurpose pumps.

Like a diamond

This pump holds several records that underline its robustness: One customer, for example, had one in use for over 22 years – during this time only seals and oil were due. Another used 650 of this and another model in a single construction project. Maintenance is simple and can be done by the customer. For example: Just loosen four screws and the impeller can be changed – if it should ever be necessary.
