PL liquid ring stainless steel centrifugal pump

Key Features

Flow rate up to 265 lt/min
Head up to 60 mt
Operating temperature max 110°C
Operating pressure max 7 bar
Motors from 0.3 HP to 6 HP - 1400/2800 RPM
Entirely made of AISI 304/316 high thickness stainless steel
Suitable for aggressive liquids

High thickness pump casing High thickness steel (3 mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life Small size Extremely compact and lightweight pump, still maintaining its performance and high efficiency Reduced speed Some models are supplied with a 1400 RPM motor, which ensures a softer and more gentle pumping action Flow reversibility On request, a motor that can reverse its direction of rotation is supplied, to ensure full flow reversibility Flammable liquids For handling flammable liquids, explosion proof motors compliant with Atex standards are supplied Maximum hygiene The pump casing is internally and externally polished to ensure the highest level of hygiene and hydraulic efficiency

Stainless steel impeller The impeller is made from microcasting of AISI 304 or 316 stainless steel. Its shape has been optimised to ensure a high hydraulic efficiency Greater safety To ensure a greater safety, the pumps with Atex motors are fitted only with motors certified to operate in more hazardous environments (zone 2 category 2G), although the pump is classified for zone 2 category 3G

The P/L series pumps have the following features:

Priming at a depth of up to 5 m with the pump filled
Flow reversibility available on request
Suitable for handling aggressive liquids
High thickness steel (3mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life
High hydraulic efficiency
Explosion proof motors can be provided to pump flammable liquids
Microcast impeller from AISI 304/306 stainless steel
Mechanical seal with NBR, FPM or PTFE elastomers

Their resistance to chemical aggression makes them suitable for the chemical, pharmaceutical and textile industry, while their versatility makes them suitable for the wine-food industry. On request, pumps can be supplied on a stainless steel carriage fitted with a switch/rotation direction inverter. The pumps can also be supplied with DIN 11851, Garolla or Macon fittings.
