P/L series
Side channel 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 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
Zone at risk of explosion
To operate in zones at risk of explosion, 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 allow using P/L pumps in potentially explosive environments Atex motors are supplied
The P/L series pumps have the following features:
- Flow reversibility available on request
- Possibility to handle 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.
