External Gears
A wide choice of construction materials and sealing elements allows its use in a wide range of applications with pressure, temperature and viscosity conditions.
The constructive accuracy makes the self-priming pumps, pulsation-free and bidirectional.
The most commonly pumped liquids are: chemicals in general, adhesives and sealants, synthetic fibers, paints and solvents, polyurethanes and resins, polymers and extruded products.

Eco Gearchem
The volumetric volumetric pumps with bi-directional self-priming parallel gears are suitable for transferring and dosing clean, lubricating and non-lubricating products. Thanks to the wide choice of materials, this pump is particularly suitable for the dosing of chemical products as an alternative to piston or membrane pumps where a linear and pulsation-free flow is essential.
The construction materials are: AISI 316, Alloy 20 and C (for highly corrosive liquids).
The sealing members can be a packing, single or double mechanical seal.
- Max Flowrate: 210 l/min
- Max Viscosity: 100.000 cPs
- Temp. Max: 230°C
- Max Pressure: 7 bar / 10 bar

Eclipse
The volumetric dosing pumps with magnetic drive of the ECLIPSE series, in addition to being made of ù very few components, are entirely made of non-metallic material. The Eclipse series is particularly suitable for dosing chemicals and is an excellent alternative to diaphragm metering pumps. For low flow rates and high operating pressures, they are also preferable to centrifugal pumps due to their high volumetric efficiency.
- Max Flowrate: 125 l/min
- Max Viscosity: 100.000 cPs
- Temp. Max: 230°C Metallica
- Max Pressure: 10 bar
For high precision and high pressure
The volumetric metering pumps with parallel gears for high pressures are used for microdosing of clean and lubricating fluids. The fields of application are the adhesives and sealants industry, synthetic fibers, paints, polyurethanes, resins, polymers and extruded products. The construction materials are: AISI 440 B – Tool Steel – AISI 316. The sealing systems can be mechanical seal and magnetic drive.
- Max Flowrate: 10.000 cc/min
- Max Viscosity: 1.000.000 cPs
- Temp. Max: 500 °C
- Max Pressure: 200 bar
Spur gear
The “spur gear” volumetric pumps with external gears are ideal for transferring small volumes at high pressures for clean, lubricating and non-lubricating products. An important feature of this series is the possibility of combining two heads that allow simultaneous pumping of two different products. Available materials: Cast iron, spheroidal cast iron and carbon steel. Sealing organs: Lip seal, single or double mechanical seal and magnetic drive.
- Max Flowrate: 720 l/min
- Max Viscosity: 250.000 cPs
- Temp. Max: 230°C Metallica
- Max Pressure: 34 bar
