The pump is in vertical design located below/alongside the drowning vessel and is fitted with a unique mechanical seal system that outsmarts the sealing arrangement of a conventional horizontal centrifugal pump. The current version of the pump has evolved after extensive usage and after taking into consideration the suggestions of a host of plant personnel from the user industry . Advantage: This unique design caters to the initial fast-filling requirement of the filtration process while ensuring automatic gradual reduction of the flow rate towards the end of filtration cycle. Unlike a horizontal pump, this vertical pump is not amenable to any damage at the end of filtration as the excess flow is fed back to the suction stream through the overflow port which acts as an in-built bye-pass system.        The mechanical seal is under slight vacuum when the pump is in operation; this action keeps the solids-entrained fluid away from the seal faces thus increasing seal life. Even during seal failure, the pump does not suffer from any breakdown problem as the corrosive fluid does not spill out allowing filtration operation to continue unhindered.

Vertical Glandless pumps are best suited for any recirculation application (scrubbers for flue gas desulphurisation, Tail Gas treatment, toxic gas removal; acid recirculation in pickling lines, anodizing & electroplating units, fine slurry spray systems etc). These are also ideal for lifting raw chemical effluents (any pH & with solid particles) from the pits (priming pot eliminates the need for a problematic foot-valve system). Keep environment clean by scrubbing almost any gas. No mechanical seal or gland packing. Leak-proof pumping of corrosive & abrasive fluids acids, alkalies, effluents, solvents. Continuous running with no maintenance hassles. Dry Running? No Problem! Mounted outside suction tank - Easy to handle.     We offer the pump with priming pot arrangement instead of foot-valve. Such applications are being successfully operated at several plants. Thus what you achieve is leakless pumping with no maintenance headaches associated with foot-valves. The unique design of the pump with priming tank offers following unmatched advantages over a vertical submersible or horizontal centrifugal pump: Outside mounting makes the pump easily accessible for operation and maintenance. There is thus no need to dismantle the whole system when a part has to be replaced or any other minor maintenance job is to be carried out. Positive suction so provided renders the pumps useful in lifting liquids from 5M depths. Current Range: Capacity to 600 M3/H, Head to 80 M.

Pumps are made generally to DIN 24256 in back-out design. All wetted parts (volute casing, back cover, impeller) are pressure-cast to shape in solid sturdy construction in UHMWPE - the toughest polymer exhibiting superior properties such as: Widest chemical resistance- nearly all chemicals (acids, alkali, salts, reagents etc.) Withstand higher temperature - 90oC. Toughest at sub-zero! Highest abrasion resistance of all polymer materials - matching exotic alloys! Exceptional impact strength - pump parts don't crack!     Impeller is semi-open type with metal bush moulded insitu, which does not dissociate from polymer due to the thrust and torsional loads of its motion. Pressure casting of uhmwpe parts of the pumps in special moulds ensures interchangeability and standardization, results in regular smooth contours of volute and impeller vanes. There are no threaded or welded joints in the wetted parts.    Shaft sealing is provided through suitable mechanical seals of reputed make, some especially designed for our pumps to suit corrosive & abrasive fluids. Shaft sleeve is made from compatible materials such as Hastelloy, Alloy-20, SS-316, Ceramic etc.
