GIGAPAS Series
Side channel self priming stainless steel pump for delicate or aggressive fluids

Flow rate up to 435 lt/min
Head up to 40 mt
Operating temperature max 110°C
Operating pressure max 7 bar
Motors from 2 HP to 7.5 HP – 700/900/1400 RPM
Entirely made of AISI 316 high thickness stainless steel
Suitable for aggressive liquids
Self-priming pump
Side channel self priming pump able to handle liquids with dissolved gases and to operate at a depth of up to 6 metres
Reduced speed
The low speed motor ensures a gentle pumping action for delicate or viscous liquids
High hydraulic head
The high efficiency of the pump allows high hydraulic heads to be achieved despite the use of low speed motors

High thickness pump casing
High thickness steel (4mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life
Zone at risk of explosion
To operate in zones at risk of explosion, motors compliant with Atex standards are supplied
Flow reversibility
The GIGAPAS series ensures a full low reversibility
Stainless steel impeller
The impeller is made from microcasting of AISI 316 stainless steel. Its shape has been optimised to ensure a high hydraulic efficiency


Maximum hygiene
The pump casing is internally and externally polished to ensure the highest level of hygiene. In addition, the internal surfaces are smooth and with no sharp edges to provide a high hydraulic efficiency
Greater safety
To allow using GIGAPAS pumps in potentially explosive environments Atex motors are supplied

The GIGAPAS series pumps have the following features:
- Priming at a depth of up to 6 m with the pump filled Flow reversibility
- Flow reversibility
- Suitable for handling aggressive liquids
- The low speed motor ensures a gentle pumping action for delicate or viscous liquids
- High thickness steel (4 mm) 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 316 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 rotation direction inverter.
The pumps can also be supplied with DIN 11851, Garolla or Macon fittings.
