The PSF series pump is a high-head pump that features a multi-vane, closed impeller, making it an ideal choice for pumping screened liquids or those without suspended solids.
The pump is constructed with special resin and stainless steel materials, which provide excellent corrosion resistance and make it lightweight. This design ensures that the pump is highly durable and can withstand harsh conditions.
Overall, the PSF series pump is an efficient and reliable option for those seeking a high-head pump that can handle a variety of liquids without suspended solids while offering resistance to corrosion and durability.

• Draining treated water at small-scale wastewater
treatment facility
• Pumping rainwater and springwater from basement
• Supplying treated water for defoaming at small-scale
wastewater treatment facility
• Circulating water in waterscape garden
(e.g. waterfall, fountain, koi pond, etc.)
The impeller is also referred to as shrouded impeller, as it has circular shrouds at both sides of the impeller vanes. Although the pump has a limited solids passage capability, it can be used for higher pumping head applications.
TOK Application Table
| Model | Applicable Motor Output |
|---|---|
| TOK4-P | 0.25 to 0.75kW |
| TOK2-65 | 1.5kW |
| TOK2-65T | 2.2 to 3.7kW |
Accessories
• Duckfoot Bend
• Guide Hook
• Guide Support with Bolts & Nuts
• Lifting Chain with Shackles (4m for TOK4-P, 5m for TOK2-65 / 65T)
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.
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.
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.
