Gear Pumps

We offer explosion proof and seal-less pumps for the petrochemical industry, pumps with minimal surface roughness for the pharmaceutical and food industry and high pressure pumps for dynamic applications etc.

External gear pumps are self-priming, non-pulsating and reversible pumps that work best on clean, lubricating fluids with a viscosity thicker than water. Two gear teeth, one idler and one driver, mesh together to transfer the liquid.

Areas of application:

Food industry:
Vegetable oils, butter, vegetable butter – margarine, treacle, chocolate, fondant, flavours, liquorice, chewing gum, vitamins, syrups, gelatine, etc.

Pharmaceutical and cosmetics industry:
Amino acids, skin solutions, shampoos, vitamins, etc.

Chemical and petrochemical industry:
Alcohols, additives, bases, esters, glycerines, resins, hardeners, isocyanates, oils, monomers, phenols, acids, biodiesel, asphalts, bitumens, tar, glues, paraffins, etc.

Polymers:
Cellulose acetate, Nylon 66, monomers, oligomers, prepolymers, PS, PET, PBT, PA, PVC, PC, PS, SAN, ABS, PUMMA, HDPE, LDPE LLDPE, HIPS, PP, PE, PEEK, POM, polysulfones, biopolymers, etc.

Metering/Dosing system (WDS):
Enables accurate volume measurement of low and high viscosity media even at high pressures and temperatures. The system consists of two gear pumps connected in series. One pump is for measuring and the other one for increasing pressure. The system is precisely controlled by a PLC control system with an accuracy of less than 0.01% according to the medium.

Special pumps:
Pumps made of ceramics, tantalum, titanium, submersible pumps, with magnetic drive, for highly corrosive media and other special designs according to customer requirements.
