A gear pump is a type of positive displacement (PD) pump. It moves a fluid by repeatedly enclosing a fixed volume using interlocking cogs or gears, transferring it mechanically using a cyclic pumping action.

Advantages of gear pumps
1. Simple and compact structure, small volume, light weight, small space occupied.
2. good workmanship, easy to manufacture, inexpensive.
3. strong self-absorption, insensitive to fluid contamination, suitable for conveying high viscosity fluids.
4. large speed range, shock load resistance.
5. reliable operation, low maintenance costs.
Application Areas
The individual media that can be conveyed with gear pumps include, among others:
• Chemical industry: alcohols, additives, bitumen, tars, wax, acids and bases, esters, glycerin, resins, isocyanate, adhesives, monomers, oils, and phenols
• Polymer manufacturing and processing: PET, PBT, PS, ABS, PVC, PE, PEEK, cellulose, nylon, and other polymers
• Food / feed processing: plant oils, butter and margarine, flavorings, chocolate, licorice, chewing gum mass, syrup, honey, gelatins, mustard and ketchup, sugar solutions, enzymes
• Pharmacy: amino acids, lotion, shampoo, vitamins
Engineered for exceptional reliability and efficiency, our Rotary Gear Pump is a robust positive displacement (PD) solution designed to handle a vast range of viscous fluids with precision. Built with interlocking, hardened steel gears and a sealless design, it ensures leak-free operation, minimal maintenance, and extended service life even under demanding conditions.

Our Rotary Gear Pump delivers outstanding performance across diverse applications:
- Broad Capability: Handles viscosities up to 5,000 mPas and temperatures from -20°C to +200°C, making it ideal for chemicals, polymers, food processing, and pharmaceuticals.
- Superior Efficiency: Offers a flow rate of 0.4–72 m³/h and pressure up to 10 bar, with self-priming functionality for flexible installation.
- Durability: Constructed with corrosion-resistant materials, it operates seamlessly in pH values of 0–14 and conveys media with solids up to 1% (6 mm max).
Key advantages of our Rotary Gear Pump include its compact, space-saving design, insensitivity to fluid contamination, and compatibility with ATEX standards (Ex Zone 1 & 2) for safe use in hazardous environments. Whether driven by electric or hydraulic systems, it provides smooth, pulse-free transfer, reducing energy consumption and operational costs.
Ideal for transferring acids, oils, syrups, resins, and more, this pump ensures consistent performance where others fail. Custom configurations are available to meet specific OEM or process requirements.
