Gear pump range extended
Gear pump range extended
Keywords: Michael Smith Engineers, Pumps
The Liquiflo 3 Series range of external gear pumps has recently been extended allowing the introduction of the 39 Series pump. This new model, available in the UK through Michael Smith Engineers, can be supplied with either leak-free magnetic couplings or conventional mechanical seals or packing.
Like the other models in the Liquiflo range, the 39 Series is said to deliver very accurate and pulse-free flows, so it is thought to be ideally suited to metering applications as well as low flow/high pressure liquids transfer duties. The pump, which is said to deliver flows up to 80l/min at differential pressures up to 7 bar, can be close coupled to electric motors or mounted on a base plate with a flexible coupling and a motor.
The 3 Series of pumps is available with a wide choice of seals, in a variety of materials and with options for trimming the gears to cover high viscosity or high temperature applications. These features, plus a choice of coatings which extend the life of the pump's wearing parts, are said to mean that, regardless of how arduous or difficult the application is, the 39 Series pump can be tailor-made to suit.
The unit pictured (Plate 7) is a magnetically coupled 39 Series pump complete with air motor which has been used to return condensate from a flare stack.

39 air-driven gear pump from Michael Smith Engineers
This version has tungsten carbide coated shafts due to the low viscosity of the solvents being handled. It is designed to handle a variety of volatile organic solvents including acetic acid and ethyl acetate and is fitted with an air motor due to the hazardous nature of the location where it is operating.
The pump will be driven by an on-site nitrogen supply and the motor is fitted with a special exhaust silencer to reduce the noise level to 81dba. Liquiflo 39 Series pumps are available in stainless steel and Hastelloy C bodies, with a wide choice of gear, wear plates and bearing material.
