Positive Displacement Pumps

Positive displacement pumps create suction lift to push fluid mechanically through the system at a constant speed, regardless of inlet pressure. Positive displacement pumps are popular in water treatment, oil and gas, chemical and food and beverage industries due to their ability to operate effectively under high viscosity, high pressure, and differential flow operations.

Flo-Line is a proud partner of industry leading positive displacement pump manufacturers such as Pulsafeeder, Netzsch, Circor, Yamada, Abel, and more. Depending on the solid content or toxicity of the fluid, our extensive range of pumps offers a solution for every process need.

Features of Positive Displacement Pumps

Along with centrifugal pumps, positive displacement pumps are one of the main types of pumping and fluid transfer solutions available for commercial applications. These pumps are typically used in cases where a constant flow rate is required.

The chambers within positive displacement pumps hold a fixed volume of liquid dependent on the requirements of your application, allowing them to transfer fluid at a constant pressure. We offer several variations of positive displacement pumps, including diaphragm pumps, progressive cavity pumps, rotary lobe pumps, gear pumps, and more.

Industrial Positive Displacement Pumps from Leading Manufacturers

Diaphragm Pumps

Diaphragm pumps use a thermoplastic, rubber, or PTFE diaphragm and valves to transfer fluids. Flo-Line offers air-operated, electronic, mechanical & hydraulic diaphragm pump designs. Typical industries include:

Progressive Cavity & Rotary Lobe Pumps

Rotary lobe pumps contain two lobes that rotate in opposite directions to create the pressure change necessary to induce fluid movement. Similarly, progressive cavity pumps use rotary motion push fluids through the system, but are often larger in size compared to lobe pumps. Both rotary lobe pumps & progressive cavity pumps are designed to handle difficult material including slurry, sewage sludge, food and drink, oil, viscous chemical pumping, and more. Ideal industries include:

Chemical
Municipal Cake Systems
Pulp & paper
Pharmaceutical
Offshore plants & more

Gear Pumps

Gear pumps are a subset of positive displacement pumps that use two or more gears to force a constant amount of fluid through the pump. Flo-Line offers a variety of innovative models for a range of industries, including:

Chemical
Food & beverage
Pharmaceutical
Extraction
Industrial Manufacturing
