Tsurumi Pump Automatic HSZ2.75S Submersible single-phase portable drainage pump that come with high volume drainage capability. With high volume drainage performance, they are suited to specifically meet the needs of the rental market, as well as the civil engineering and the construction market.
The HSZ series is made as a simple float switch-equipped automatic model to prevent dry running operation and to reduce power consumption.
Features :
- Anti-wicking cable entry
Prevents water incursion due to capillary action should the cable sheath be damager or the end of cable submerged. Also prevents moist air from infiltrating the motor housing and condensation from forming inside the housing due to temperature differences between the housing and outside air. - Dual inside mechanical seals with silicon carbide face
Eliminates problems like spring failure and ensure a long service life. Isolated in the oil chamber where a clean, non-corrosive and abrasion-free lubricating environments is maintained. The silicon carbide provide 5 times higher corrosion, wear and heat resistance than tungsten carbide - Oil lifter
Provides lubrication and cooling of the seal faces down to 1/3 of normal oil level, thus maintaining a stable shaft sealing effect and prolonging seal life longer. The oil lifter is Tsurumi original design. - V-ring (0.75 kW only)
Used as a “Dust Seal” they protect the mechanical seal from abrasive particles - Agitator
Prevents the air lock that tends to take place on vortex or semi-vortex pumps.
