Manufacturer of Gear Pumps & Centrifugal Pumps

Since 1972, Liquiflo has manufactured high-quality Gear Pumps and Centrifugal Pumps, specifically designed to
meet the demanding needs of the chemical industry.  Liquiflo pumps are made from high-alloy materials such as
316 Stainless Steel, Alloy-C, Alloy-20 and Titanium.  By offering a large selection of corrosion-resistant internal materials and multiple sealing options - such as mechanical seals and magnetic-drives - Liquiflo pumps are capable of pumping a wide range of chemicals - including acids, caustics, solvents and polymers - over a wide range of conditions.

Gear pumps are self-priming positive displacement pumps that produce a non-pulsating flow and require lower NPSH (net positive suction head) to operate. They are ideal for metering applications and for pumping nonabrasive, viscous liquids at high differential pressures.  Liquiflo has extended the useful range of gear pumps into low-viscosity fluids by using a wide variety of non-metallic, self-lubricating components. Liquiflo gear pumps have handled thousands of difficult chemicals and have been successfully applied in many difficult pumping situations, including
high-viscosity, high-pressure and high-temperature applications.

Liquiflo gear pumps are a popular alternative to other pumping technologies, such as Diaphragm pumps, Progressive Cavity pumps, Peristaltic pumps and Piston metering pumps.  Gear pumps are an alternative to Diaphragm pumps because they do not pulse or require an expensive air source to operate. For metering applications, they do not require pulsation dampeners or other ancillary equipment. In continuous duty applications, they generally last longer than Diaphragm, Progressive Cavity or Peristaltic pumps, which require frequent part replacement, such as diaphragms, stators, rotors or hoses. Gear pumps have a simple principle of operation which makes them easy to understand and repair.

Liquiflo offers a large selection of standard pumps, kits, parts, options and accessories, which are available for immediate delivery. In addition, Liquiflo can customize pumps to meet your specific needs.

Our experienced application engineers, customer service representatives and worldwide network of distributors are available to assist you with your special chemical pumping applications.
