TR 3 - 4 HP three-phase submersible electric pump with grinder
Flow rate up to 400 l/min (24 m³/h). Head up to 34.5 m. 3 Kw (4 HP) motor.
The three-phase grinder pump TR 3 by Pedrollo is recommended for use in the domestic and industrial sectors.
The fundamental characteristic of this pump is its construction.
The TR 3 has a pump body made of cast iron of considerable thickness and a grinder made of high-resistance tempered stainless steel which allows for the complete grinding of solid bodies and fibres contained in waste water and effluent in the domestic and civil sectors, for conveyance under pressure into the sewer system through small diameter pipes.
It must be powered by a three-phase voltage, has a horsepower of 4 HP and the temperature of the liquid to be pumped reaches up to +40 degrees centigrade.
The pump can be used up to 10 meters deep below the water level.
It has a flow rate that varies from 20 to 400 litres per minute with a head from 2 to 34.5 metres.
The TR 3 pump is supplied with a 10 metre H07 RN-F power cable.
It can be used with various coupling kits supplied by Pedrollo .
