Diaphragm Pumps:

Diaphragm pumps use a flexible diaphragm to create pressure and flow. The diaphragm is typically made of rubber or thermoplastic material, and is moved back and forth by a mechanism to create suction and discharge strokes. They are commonly used in applications that require low flow rates and high pressures, as well as in applications where the fluid being pumped is corrosive or abrasive. Diaphragm pumps can handle temperatures ranging from -40°C to 200°C and pressures ranging from 0.2 bar to 7 bar. They are often used in the chemical, pharmaceutical, and food and beverage industries. One of the main benefits of diaphragm pumps is their ability to handle a wide range of fluids, including viscous and abrasive liquids.

Gear Pumps:

Gear pumps use meshing gears to create flow. As the gears rotate, they create pockets of fluid that are carried from the inlet to the outlet of the pump. They are commonly used in applications that require low flow rates and high pressures, as well as in applications where a constant flow rate is required. Gear pumps can handle temperatures ranging from -40°C to 200°C and pressures ranging from 0.1 bar to 350 bar. They are often used in the chemical, pharmaceutical, and food and beverage industries. One of the main benefits of gear pumps is their simplicity, as they have only two moving parts and require minimal maintenance.

Vane pumps can handle temperatures ranging from -20°C to 200°C and pressures ranging from 0.5 bar to 25 bar.

Peristaltic Pumps:

Peristaltic pumps are positive displacement pumps that use rotating rollers to compress and release a flexible tube, creating a vacuum and drawing fluid into the tube. They are capable of pumping a wide range of fluids, including abrasive and viscous fluids, and are often used in applications where contamination or product degradation must be avoided. They are also commonly used in the medical and pharmaceutical industries. The operating temperature and pressure range of peristaltic pumps depends on the material of the tubing used. They can handle pressures up to 100 psi and temperatures up to 212°F (100°C).

Piston Pumps:

Piston pumps are positive displacement pumps that use reciprocating pistons to move fluids through a cylinder.

They are commonly used in applications that require high viscosity or shear-sensitive fluids, such as food processing, wastewater treatment, and oil and gas production. The operating temperature range of progressive cavity pumps is typically between -40°F (-40°C) and 300°F (149°C), and they can handle pressures up to 6,000 psi.

Regenerative Turbine Pumps:

Regenerative turbine pumps are centrifugal pumps that use a rotor with multiple vanes to generate high pressure and flow rates. They are commonly used in applications that require high pressure, such as refrigeration and air conditioning systems, and can handle pressures up to 2,000 psi and temperatures up to 500°F (260°C).

Axial Flow Pumps:

Axial flow pumps are centrifugal pumps that use a propeller-like impeller to move fluid in a axial direction. They are commonly used in applications that require high flow rates, such as flood control, irrigation, and cooling systems. Axial flow pumps can handle pressures up to 100 psi and temperatures up to 200°F (93°C).

Mixed Flow Pumps:

Mixed flow pumps are centrifugal pumps that combine the features of radial and axial flow pumps to generate a hybrid flow pattern. They are commonly used in applications that require high flow rates and moderate pressure, such as water supply systems and irrigation. Mixed flow pumps can handle pressures up to 200 psi and temperatures up to 200°F (93°C).

Eductor-Jet Pumps:

Working principle: Eductor-jet pumps use a high-velocity jet of fluid to create suction and entrain another fluid or gas. They do not have any moving parts. Operating temperature and pressure range: They can handle temperatures from -20°C to 400°C and pressures up to 1,500 psi. Applications and benefits: Eductor-jet pumps are commonly used in the chemical, petrochemical, and process industries for mixing, pumping, and circulating fluids. They are easy to install, have low maintenance requirements, and can handle fluids with high solids content or viscosity.

Lobe Pumps:

Working principle: Lobe pumps use two or more rotating lobes to transfer fluid from the inlet to the outlet. The fluid is trapped between the lobes and the pump casing and is transported around the casing to the discharge port. Operating temperature and pressure range: They can handle temperatures up to 150°C and pressures up to 20 bar. Applications and benefits: Lobe pumps are commonly used in the food, beverage, and pharmaceutical industries because they can handle delicate fluids without damaging them.

Magnetic Drive Pumps:

Working principle:

Magnetic drive pumps use a magnetic coupling to transfer power from the motor to the impeller. The impeller is enclosed in a hermetically sealed casing, which eliminates the need for a shaft seal. Operating temperature and pressure range: They can handle temperatures up to 150°C and pressures up to 20 bar. Applications and benefits: Magnetic drive pumps are commonly used in the chemical, pharmaceutical, and semiconductor industries because they are leak-proof and do not emit any harmful vapors.
