P/L series
Liquid-ring stainless steel centrifugal pump
The P/L series pumps have the following features:
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.
Liquid-ring stainless steel centrifugal pump

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 lifeSmall size
Extremely compact and lightweight pump, still maintaining its performance and high efficiencyReduced 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 reversibilityFlammable liquids
For handling flammable liquids, explosion proof motors compliant with Atex standards are suppliedMaximum hygiene
The pump casing is internally and externally polished to ensure the highest level of hygiene and hydraulic efficiencyStainless 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- Priming at a depth of up to 5 m with the pump filled
