Sanitary POSITIVE DISPLACEMENT PUMP

Is a positive displacement pump the right option for you?

Do you want transfer high viscosity fluids?
Do you want Pumping fluids containing substantial solids, slurries, and pastes?
Does your application require a self-priming suction lift?
Do you need a measured flow or constant pressure at different flow rates?

Positive displacement pumps are used to transfer high viscosity fluids at high pressures and relatively low flows.
Usually selected for their ability to handle fluids with particles and soft solids.
VISCOSITY RANGE up to 1,000,000 CP

Twin Screw Pumps

Circumferential Piston Pumps

Rotary Lobe Pumps In Stock

Is the latest generation "2-in-1" pump, delivering the benefits of both positive displacement pumps and centrifugal pumps.
Save time and cost because pumping and cleaning are processed within a single pump.
Handle low and highly viscous fluids, pastes and fruit particles within a juice.

This pump will handle high viscosity products and settled slurries that jam up lobe pumps or progressing cavity pumps with ease. It also imparts very low shear forces to the pumped product, far lower shear than lobe pumps or progressive cavity pumps.

Rotary lobes have the ability to handle highly viscous fluids, pastes and handle fluids containing soft solids without causing any damage.

Flexible Impeller Pumps

Progressive Cavity Pumps

Flexible impellers handle low and high viscosity fluids, gels and pastes and carefully can handle fluids containing hard and soft solids. 

Progressive cavity pumps are used to transfer products of low and high viscosity as well as products containing soft particles.

application examples

CENTRIFUGAL PUMPS

Centrifugal pump remains the workhorse of the food and beverage industry, It is widely used for transferring wine, beer, milk, juices, soft drinks and many others fluids with low viscosity.

Rotary Lobe Pumps

Used for transferring sauces, salad dressing, dough, oils, concentrates, chocolate, fondant, ketchup, liquid egg, cream, yogurt, cheeses, mayonnaise, syrups and many others.

FLEXIBLE IMPELLER PUMP

It is widely used for transferring wine from one collecting tank to another and also for transferring must, sauces, dough's, liquid egg, meat pastes, milk, cream, yogurt, cheeses, beers, soft drinks, fruit juices, syrups and many others.

PROGRESSIVE CAVITY PUMP

Used for transferring whole or destemmed grapes, jam, marmalade, pasta, yeast, ketchup, dough's, pate, liquid egg, milk, cream, yogurt, cheeses, mayonnaise, syrups and many others.

TWIN SCREW PUMP

Used for transferring pulp, concentrates, chocolate, fondant, mashes, yeast, ketchup, dough's, pate, liquid egg, milk, cream, yogurt, cheeses, mayonnaise, syrups and many others.
