Submersible Seawater Pump TM Series

The TM series is a highly durable semi-vortex pump constructed of titanium and special resin. This design allows for exceptional resistance to corrosion, making it an excellent choice for handling seawater. The entire pump is made of titanium, including all of the wetted metal parts, which makes it highly suitable for various applications involving the intake, transfer, and drainage of seawater.

The TM series is ideal for pumping seawater from bilges and pits of vessels. It can also be used for supplying seawater to aquariums, as well as for circulating seawater in breeding ponds. Its exceptional durability and resistance to corrosion make it an excellent choice for these demanding applications.

TYPE OF IMPELLER

Vortex imeller
Vortex

The vortex impeller is adopted in every series except for the PSF-series. Rotation of the impeller produces a whirling, centrifugal action between the impeller and the pump casing, and it moves the fluid through the pump. Being coupled with a wide pump casing, wastewater containing solid matters can be pumped out without obstruction.

MODEL NUMBER DESIGNATION

SUBMERSIBLE SEWAGE PUMP DESIGN

TOK GUIDE RAIL FITTING SYSTEM

The TOK guide rail fitting system connects the
pump to and from the piping easily just by lowering
and hoisting the pump, allowing easy maintenance
and inspection without the need to enter the sump.

Made of high-quality resin, the TOK is designed
for lightweight, small to middle sized pumps.
Rubber bellows attached to the guide hook are
inverted to the duckfoot bend when the pump
starts operating, and it seals by the pumping
pressure. This eliminates leakage at the seal
even if a lightweight pump is used in combination
with the TOK.

The TOK is available in all motor output ranges of
the PU, PN, and PSF series.

AUTOMATIC & AUTO-ALTERNATION MODEL

Automatic Model

The float type automatic model has an integral control circuit and two float switches that operate at a low voltage. It operates automatically in response to the change in water levels.

This model can be identified by the suffix “A” and is availa-ble in all motor output ranges of the PU, PN, PSF, and TM series.

The cylindrical float type automatic model is available only for the OM-series. Adoption of the unique float switch has made even the automatic model very compact and enables it to be installed in a limited space. Automatic operation is possible with a simple power panel.

Auto-alternation Model

The auto-alternation model is used along with an automatic model. The combinational use of these two pumps enables each pump to operate alter- nately without control panel.

The auto-alternation model has three floats and can be identified by the suffix “W”. Refer to model selection for availability and model num- bers of the PU, PN, and PSF series.
