Many types of pump available

Pump Systems, Ltd, in Wordsworth Street, can offer a complete range of pumping equipment and accessories for any type of industrial or domestic requirement. Included in the range are the following five major product lines: DPN multi-stage centrifugual pumps: This is a new range of multi-stage pumps with stainless steel impellers, diffusers and sleeve. The vertical DPN pumps make extensive use of stainless steel to give durability and high efficiency. The pumps can be delivered in seven different models which can each be equipped with one, up to 20 stages for achieving optimum results, i

Among the advantages of vertical pumps is the fact that they take up little space and operate quietly. The pumps are standard equipped with 2850 rpm motors and are normal priming, suitable for continuous running without appreciable maintenance. There are a wide variety of applications: booster sets, boiler feeds, jocky pumps for sprinklers, carwash installations, airconditioning, circulation and transport. Diesel engine pumpsets: The company designs, makes, installs, and commissions diesel engine pumpsets, using Hatz diesel engines coupled to Indeng end-suc-tion centrifugbal pumps mounted on a chassis. Manufactured by Andrews and Beaven Manufacturing Company in Christchurch, the Indeng end-suction pumps have many applications, ranging from fire-protection in industrial use, through municipal water supplies, to agricultural application in stock dipping, I Amiad filters, from Israel, come in all sizes, types and capacities. They are avail-

able for drip, trickle, microjet sprinklers and sprinkler systems. The filters reflect the increasing use of high technology by the use of a variety of materials, ranging from special chemical-resistant plastic to epoxy-coated metal filters. This makes the Amiad filters useful in industrial and domestic areas as well as on farms. Amiad has also developed a three-quarter inch filter with a carbon element to remove organic matter so that the water can be used for drinking. Sarlin Submersible Pumps: Jamming and clogging is a problem in the pumping of crude sewage and effluents which contain solids. Sarlin submersible pumps, which are available in five different versions, have been especially developed to cope with the demands made on pumps used for pumping raw sewage, industrial effluents, sludge and other types of contaiminated waters containing solids. All Sarlin-S pumps have a self-cleaning axial clearance, so that impurities which get into the clearance go back into the suction inlet of the pump. Impellers with auxiallary vanes eliminate back-flow. The pumps can either be installed permanently or be portable, and completely or partly submerged in the liquid which is to be transferred. Wilden Pumps: These are versatile pumps which can transfer among other things, dry powders, latex, food products, sewage sludge, corrosive chemicals. The air-operated, doublediaphragm pump was pioneered more than 27 years ago. It can be used in permanent, submerged, or self-priming installations, either fixed or portable.
