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

The high-efficiency rotary gear pump builds on the proven advantages of traditional gear pump technology while incorporating optimized hydraulic design and precision manufacturing to deliver superior performance. Its compact and lightweight structure allows easy installation in space-limited systems, while the simple mechanical layout reduces the number of wearing parts, ensuring long-term reliability and cost-effective operation. These characteristics make it an ideal choice for continuous-duty industrial environments where stability and durability are critical.

Thanks to its strong self-priming capability and insensitivity to fluid contamination, the high-efficiency rotary gear pump performs reliably even when handling challenging media. It is especially well suited for high-viscosity fluids, maintaining steady flow rates without cavitation or loss of efficiency. The wide speed range and excellent resistance to shock loads allow the pump to adapt to fluctuating process conditions, ensuring consistent output and protecting downstream equipment.

Energy efficiency is a key advantage of modern rotary gear pumps. Improved gear profiles, tight internal clearances, and optimized flow paths minimize internal leakage and mechanical losses. As a result, the pump delivers higher volumetric efficiency while consuming less power, helping operators reduce energy costs and meet sustainability goals. The sealless design further enhances safety by eliminating leakage risks, making the pump suitable for hazardous, toxic, or environmentally sensitive fluids.

With ATEX certification for Ex Zone 1 and 2, the high-efficiency rotary gear pump can be safely deployed in explosive atmospheres commonly found in chemical and petrochemical plants. Flexible drive options, including electric and hydraulic drives, allow seamless integration into different process systems. Horizontal installation simplifies maintenance access and system layout.

Across chemical processing, polymer production, food and feed manufacturing, and pharmaceutical applications, the high-efficiency rotary gear pump provides precise, stable, and hygienic fluid transfer. Its ability to handle a wide range of viscosities, temperatures, and media types makes it a versatile and future-ready solution for industries seeking reliable performance, low maintenance, and long service life in modern fluid handling systems.
