Tsurumi KTVE Submersible Pumps
Tsurumi KTVE Submersible Pumps combine high tech materials for maximum durability, yet lightweight and portable. This pump is equally suited for construction site dewatering as well as installation into facilities.
Pumped water cools the motor and discharges as illustrated. The motor can be cooled even when pumping a small amount of water. The top discharge arrangement allows access into areas with space limitations.
To lower the overall weight, pump materials have been changed in part to die-cast aluminium and specially treated synthetic rubber. Compared with Tsurumi's conventional pumps of the same type, this change has resulted in a 10kg weight reduction. An ergonomically designed handle facilitates relocation of the pump at construction sites.
The pump's lower part can be disassembled with a box wrench for effortless maintenance without impeller removal.
Specially prepared synthetic rubber parts including the casing, wear plate and duct sleeve protect the die-cast aluminium motor housing. This has resulted in amazingly increased wear resistance and other virtues such as:• Reduced need for general service maintenance.• A pump immune to calcium carbonate deposits or scale
Electrode auto control systemThe KTVE-type is equipped with a new eletrode type control system. This prevents unnecessary dry operation, which makes it ideal for work environments where noise must be prevented, for example, in night operation in residential areas. Pump operating is started when the water level rises and contacts the electrode. When the water-electrode contact is lost the timer starts operating and after one minute pump operation is stopped.
