Gear pumps handle "difficult" liquids
The characteristics of gear pumps make them particularly suitable for metering and transferring "difficult" liquids, such as those that are viscous or thin.
The characteristics of gear pumps make them particularly suitable for metering and transferring "difficult" liquids, such as those that are viscous or thin As well as positive displacement pulseless smooth flow operation, the other benefits offered by gear pumps include: self-priming operation; reduced NPSHR; fewer wearing parts; flow accuracies as low as 0.5%; and ease of repair

Reliable pumps deliver smooth flows
The I-Drive pump includes a brushless DC motor with no moving parts and an electronic controller.
Pumps handle harsh fluids
The LVP range of pumps is designed to provide smooth, nonpulsating, low-shear flows and offer superior suction lift capability and a reversible direction of flow.
A good example is the Liquiflo range of magnetically coupled gear pumps, available through Michael Smith Engineers.
The 33 Series pump featured has been successfully pumping solvent based products with a range of viscosities ranging from 0.2 to 10cm2/s.
This model incorporates a patented Dual-Kan (double wall containment can) and clamp-on design temperature control jacket, making it ideal for liquids transfer applications which require precise and uniform temperature control.
Precise temperature control is commonly required when pumping liquids that solidify or become viscous when temperature decreases.
Either steam or a hot liquid can be used to circulate through the jackets and the Dual-Kan to ensure that the entire pump operates at an even temperature.
The base material for this pump is Hastelloy C276 and because of the low lubricity of the fluids being handled features a combination of silicone carbide bearings and tungsten carbide coated shafts to provide optimum life.
The pump is driven by a close-coupled 0.55kW ATEX ExD IIC T4 motor fitted with an integral frequency inverter unit, the main benefit of this being that the unit was self-contained on the customers skid.
This Liquiflo 33 Series pump is just one of a range of Liquiflo RotoGear 3 and H Series covering flow rates from 1.9 to 220 litre/min at pressures up to 15bar.
