Compact barrel pump handles aggressive inorganic chemicals

Keywords: Michael Smith Engineers, Pumps

Developed to handle aggressive inorganic chemicals such as bleach, nitric acids, hydrochloric acids and sulphuric acids, the Finish Thompson TBP series pump from Michael Smith Engineers (see Plate 2) has a reported maximum tube diameter of only 42mm which it is thought makes it suitable for use with many types of chemical containers.

Based on pure PVDF/polypropylene materials it will find many applications, wherever bleach is used in drums, barrels or other containers.

The TBP pump is designed as an economical, light to medium duty drum pump, suitable for use with containers with small bung openings. It is available with a choice of electric motors, including splash-proof, totally enclosed fan-cooled IP54 motors, as well as explosion-proof drives. There is also the option of a pneumatically powered motor for use where circumstances prohibit the use of electric ones. All the available motors are said to be certified to CSA or CE requirements.

The pump, which is said to deliver flows up to 75 litres – one minute and heads up to a maximum of 12m, is reported to be capable of handling liquids with viscosities as high as 200cps and densities of up to 1.4SG and will operate at temperatures as high as 66°C.

When powered by an electric motor, the pump reportedly handles up to 75 litres per minute with a 12m head, while the pneumatic powered version provides a maximum of 50 litres per minute with a head up to 6m.

The tubes are made from polypropyl – ne 1 PVDF, in lengths of 600mm or 1,000mm. A graphite-filled seal is incorporated and the shaft which drives the impellor at the bottom of the tube is made from alloy 625, while all the tube internals are in PTFE.

Electric motors, which are available in 115V or 230V single-phase, 50,160Hz models are equipped with a 4m length of electric lead and rated for continuous duty. The pneumatic version incorporates a silencer and operates from a supply at 80 to 100 PSI at 25 CFM.
