PRINCIPAL OF VERTICAL GLANDLESS PUMP

The “MALHAR” Pump is similar Hydraulic design to any Conventional centrifugal pump. It Differs in so far as it is always mounted in the vertical position. A Restriction is provided above the impeller and need for any from of liquid seal is obylated by allowing a small leakage to escape by way of an overflow connection in the upper pump body return to suction vessel.

The most suitable method of Installation will depend on the pumping application. The simplest and most widely adopted method is mount the pump close to the feed tank at such a level that the impeller is flooded and the pump therefore pumped when the liquid reaches a certain height in the tank.The pump will Deliver liquid until the suction pipe becomes uncovered , when it will run dry until the liquid level is restored to the point where re-printing can take place,this cycle of operation may be repeated indefinitely.

OPERATION ADVANTAGES OF GLANDLESS PUMP

• The recognizable leading improvement is the deletion of problems get to your feet from the use of powered seal, insulation box and inside bearing.
• The aptitude of pump to run dry eliminates single reason of interruption which is regularly attributable to the human component this feature is very convenient in process needing continuous transference of a corrosive fluid with a high gradation of reliability e.g. Disposal of acid effluent.
• The glandless pumps lend itself to process incorporating automatic control of a pump discharge valve. The “controlled leakage” acts as an integral by-pass. The pump suffers no ill effects if the discharge valve is partially or fully closed.
• The maximum main improvements to be derivative from the use of glandless pump are in the province of maintenance and following reduction in down time invention victims. Normal maintenance on the glandless pump is confined to lubrication of the driving.

SAILENT FEATURES OF VERTICAL GLANDLESS PUMP

• No mechanical seal, stuffing box and internal bearings provided.
• No maintenance since the pump can even run dry indefinitely as there is no packing, bushes or internal Bearings.
• Reduction of downtime production losses in view of above features.
• All the wet-end parts are in solid molded construction to with stand corrosion and erosion.
• The impeller is semi-open type used in our all-vertical pumps to suit both clear and polluted fluids.
• Pump mounted outside the suction tank and is not submerged type.
• Polypropylene are manufactured by solid injection molding process with high pressure hence.
