Positive Displacement Pump

A positive displacement pump makes a fluid move by trapping a fixed amount and displacing that trapped volume into the discharge pipe. Some positive displacement pumps use an expanding cavity on the suction side and a decreasing cavity on the discharge side. The benefit of a positive displacement pump is that the volume of liquid is constant for each operational cycle. There are many benefits of positive displacement pumps for varying applications.

Positive Displacement pumps are sometimes called constant-volume pumps because they maintain a constant speed and flow. Even if the system pressure varies, the flow remains constant.
Positive Displacement pumps can handle a variety of fluid types: high, low and variable viscosity; shear sensitive fluids; solids; and liquids with a high percentage of air or gas entrainment.
Their capacity is not affected by the operation pressure.
They can be more efficient than centrifugal pumps when handling viscous fluids.
Positive Displacement pumps are able to self-prime.
They can be designed as a sealless pump.

Positive displacement pumps have a wide variety of applications within sanitary processing markets such as:

Bakery – Dough, fats, fruit filling, icing, oil, yeast
Beverages – Beer, fruit concentrate, fruit juices, mash, wine
Confectionery – Chocolate, cocoa butter, corn syrup, gelatin, sugar
Canned Foods – Tomatoes, baby food, jams, jellies, mayonnaise, potato salad, pudding, relish, stews
Cosmetics – Creams, emulsions, jellies, lotions, shampoo, toothpaste
Dairy – Butter, cream, curds, ice cream, margarine, milk, soft cheese, yogurt
Dressings – Mayonnaise, other sauces, ketchup
Flavorings – Concentrates, syrups
Meats – Broth, fats, gelatin, pet foods, sausage fillings
