More about this product
Product overview
The Pedrollo TR 1.5 is a 1.5 kW (2 HP) submersible grinder pump for sewage on a 400 V three-phase supply, covering 20 to 270 l/min with a working head of 25 m down to 2 m. The grinder cuts solids and fibres so sewage can be pumped under pressure through small-diameter pipework.
The TRITUS is built from thick cast iron for exceptional robustness, abrasion resistance and long life. A robust hardened stainless steel blade cuts through the solids and fibres in domestic and civil waste water and sewage, with a micro-cast AISI 304 impeller, an AISI 431 shaft and a double mechanical seal in an oil chamber.

Frequently asked questions
Why use a grinder pump?
The grinder cuts solids and fibres so sewage can be pumped under pressure through small-diameter pipework into the sewer system.
What comes with the single-phase models?
A control panel (ON/OFF switch, manual-reset motor protection, run and start capacitors) and a float switch.
What do the three-phase models need?
A control panel and level control. On the TR 1.5, 2.2, 2.2 AP, 3 AP, 3 and 4, the built-in thermal protector must be connected to the panel for the warranty to apply.

Frequently Asked Questions
Quick answers to common questions about the Pedrollo TRITUS TR 1.5 Three Phase 2302370. For technical specifications, see the product details above; for sizing or installation advice, contact our team. If you have any other questions, we're happy to help.
What is a submersible pump?
A submersible pump is designed to operate fully submerged in the liquid it is moving. The motor is sealed inside the pump body and cooled by the surrounding water. Submersibles are used for drainage, sewage, septic tanks, deep wells and boreholes, and for raising water from sumps, cellars and floodwater. Many stocked at Anglian Pumping handle solids in suspension.
Can submersible pumps handle solids and sewage?
Yes – some submersibles are designed for clean water only, others handle solids up to 50 mm or full raw sewage. Anglian Pumping stocks ABS, BBC, Flygt and T-T Submersibles ranges that include vortex, single channel and grinder impellers for different solids handling requirements. Always match the pump to the maximum solid size and the type of effluent it will see.
When should I use a submersible pump instead of a surface pump?
Use a submersible when the water level is more than around 8 metres below the pump installation point – surface pumps cannot self-prime beyond that depth. Submersibles are also better when the liquid contains solids, when noise must be minimised, or when the pump needs to operate in confined spaces such as sumps and chambers where a surface pump would not fit.
