Product Description

Review the intended use, key features, and technical information supplied for this product.

Overview

The Tsurumi 50PNI2.75S is a semi-vortex resin submersible sewage pump from the PNI series. In the model code, "50" is the 50mm (2") discharge bore, "PNI" the vortex-type resin pump series, "2" a 2-pole motor, ".75" the 0.75kW (1HP) motor output and "S" the single-phase version. Designed for wastewater and liquids carrying small solid matter, it uses a semi-open vortex impeller, with impeller and casing in glass fibre reinforced plastic (GFRP) and a 304 stainless steel pump body and motor frame for excellent corrosion resistance. Dry weight is only about 9.3kg, so one person can carry and install it. Liquid paraffin is used as the lubricating oil, extending its use to decorative waterfalls, fishponds and aquaculture.

Applications

Waterfalls & water features: liquid paraffin lubricant suits ornamental circulation.

Fishponds & aquaculture: corrosion-resistant resin body for continuous duty.

Basement & sump drainage: handles wastewater carrying small solids.

Small-scale sewage transfer: 10mm solids passage reduces clogging.

Operation & What Is Supplied

The 50PNI2.75S is the manual-operation model, supplied with a 10m cable attached.
No float switch is included. For automatic level control, the float set is an optional accessory ordered separately (the automatic PNI model is the 50PNI2.75SA).
