Product Description
Ajay Engineering molasses pumps are specially designed positive-displacement and centrifugal pump configurations for handling high-viscosity fluids such as molasses, syrup, treacle, and other heavy sugar solutions. Available in horizontal and vertical layouts, our pumps feature gentle handling to prevent shear and crystallization, wide clearances for solids and fibers, and food-grade materials where required.
Key design highlights:
- Smooth flow paths to reduce clogging and product degradation.
- Heavy-duty bearings and seals for long life in abrasive, sticky media.
- Modular construction for quick servicing and spare parts interchangeability.
- Optional heating jackets, stainless steel wetted parts and hygienic finishes for food applications.
Core features & benefits
- High viscosity handling: Engineered clearances and rotor/stator designs to pump molasses up to high centipoise ranges without loss of efficiency.
- Corrosion & wear resistance: Stainless steel (SS304/SS316) and special alloy options for wetted parts to resist sugar, organic acids and abrasive solids.
- Low shear operation: Gentle pumping action preserves product quality (important for syrups, enzyme solutions and food applications).
- Easy maintenance: Cartridge seals, split casings and accessible bearing housings simplify downtime and reduce maintenance costs.
- Heating jacket option: Prevents crystallization in cold environments maintains viscosity and pumpability.
- Customizable: Multiple drive options (electric motor, gearbox, couplings), flange sizes, and seals (mechanical, gland or aseptic).
- Energy efficient designs: Optimized impeller/rotor geometry reduces power draw and operating expense.
- Safety & compliance: Food-grade finishes and materials available; designed to meet hygienic and industry standards on request.
Typical applications
- Sugar mills molasses transfer, blending and storage feed.
- Distilleries molasses feeding to fermenters and evaporators.
- Confectionery and syrup production dosing and transfer.
- Breweries and beverage plants viscous adjuncts and syrups.
- Chemical and fertilizer industries viscous by-products and slurries.
- Tank unloading, tanker transfer and batching systems.
- Any process requiring hygienic handling of sticky, viscous fluids.
