Submersible Wastewater Pump PN Series

The PN series pump is a versatile semi-vortex pump that features a vortex impeller and low-height volute casing. It is designed to efficiently handle moderate solids passage, making it suitable for a wide range of applications. Moreover, the pump is constructed with special resin and stainless steel materials, which offer excellent resistance to corrosion and make it lightweight.

The PN series pump can be used for various purposes, such as draining wastewater from residential areas, hotels, and restaurants. Additionally, it can be used for pumping rainwater and spring water from basements, as well as circulating water in waterscape gardens, including waterfalls, fountains, and koi ponds.

APPLICATIONS

• Draining wastewater from residence, hotel, restaurant, etc.
• Pumping rainwater and springwater from basement
• Circulating water in waterscape garden
(e.g. waterfall, fountain, koi pond, etc.)

TYPE OF IMPELLER

The vortex impelle is 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.
