Submersible Semi-vortexDrainage Pumps

for General Construction Work2-pole Motor Series

CompactThe height has been reduced by a maximum of 181 mm (133 mm for KTV 2-15 and KTV 2-37) from Tsurumi’s conventional equivalents by eliminating unnecessary room in the motor and the pump. These pumps are the smallest in this class in the industry.

LightweightPump materials have been changed in part to die-cast aluminum and specially treated synthetic rubber. This has reduced the weight of all models in this series by more than 10 kg compared with Tsurumi’s conventional pumps of the same type. An ergonomically devised handle facilitates the relocation of the pump at a construction site.

Submersible Drainage Pumps

for General Construction Work4-pole Motor Series

RuggedKRS-series, another cast iorn pumps with 4-pole motor, represent Tsurumi’s multipurpose pumps for their simple construction, superb durability, and high efficiency. Tsurumi’s years of expertise and innovative techniques are fully utilized in every component of these pumps which have own user’s unparalleled credit and admiration.

KRS

This Oil Lifter was developed to improve quality and reliability of our submersible pump by enhancing sealing performance of the mechanical seal.

* The Oil Lifter is a lubrication device for the mechanical seal that is the heart of the submersible pump.

* The Oil Lifter stabilizes and enhances mechanical seal lubrication and cooling effect.

* Offers stable sealing performances even if the oil level drops. Facilitates periodic inspection.

Oil Lifter (Patented)

RuggedThe die-cast aluminum part is protected with the casing, wearing plate, and duct sleeve, all made of specially prepared synthetic rubber. This has resulted in amazingly increased resistance to wear and in the following additional virtues. Greatly reduced maintenance service

intervals. A pump immune to calcium

carbonate deposits or scale; if any, readily removed.

No clogging, thanks to the semi-vortex flow construction.

Low maintenanceThe pump’s lower part can be disassembled with a box wrench to facilitate maintenance services.
