Submersible Single-phase Portable Drainage Pumps
The HS3.75SL & HSZ3.75SL model pumps are submersible
single-phase portable drainage pumps that come with high volume
drainage capability. These pumps are a low head, high volume
drainage type launched under Tsurumi’s proudly best-selling
HS-series. With high volume drainage performance, they are suited
to speci�cally meet the needs of the rental market, as well as the
civil engineering and the construction market.As with the existing
HS-series units, these operator-friendly submersible pumps are
compact and lightweight, i.e. highly portable, and offer improved
maintainability. With their wear-prone parts constructed of
wear-resistant materials, they are also superbly durable. Moreover,
the shaft incorporates Tsurumi’s original agitator to prevent air
lock as occasionally seen in vortex pumps and semi-vortex pumps.
The agitator also stirs slurry ef�ciently. The HSZ-series is made
as a simple �oat switch-equipped automatic model to prevent
dry-running operation and to reduce power consumption.

Anti-wicking Cable EntryPrevents water incursion due to
capillary action should the cable sheath be damaged 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 dif ferences between the housing and outside
air.
1
Dual Inside Mechanical Seals with Silicon Carbide FaceEliminates
problems like spring failure and ensures a long service life.
Isolated in the oil chamber where a clean, non-corrosive and
abrasion-free lubricating environment is maintained. The silicon
carbide provides 5 times higher corrosion, wear and heat resistance
than the tungsten carbide.
2
Oil LifterProvides 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.
3
V-ring (0.75kW only)Used as a “Dust Seal,” they protect the
mechanical seal from abrasive particles.

AgitatorPrevents the air lock that tends to take place on vortex
or semi-vortex pumps.
