Operation Advantage of Glandless Pumps
The first and foremost benefit of this type of PP pump is, it prevents the problem caused by the gland failure and seal failure.
The ability of the pump to run dry eliminates breakdown, which makes it a preferred alternative in process demanding continuous transfer of a corrosive liquid with an utmost degree of reliability, for a while, 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 bypass. The pump suffers no ill effects if the discharge valve is partially or fully closed.
The most significant benefits to be derived from the employment of the polypropylene pump are in the sphere of maintenance and consequent decrease in down time production losses. However, Normal maintenance on the vertical glandless pump is confined to lubrication of the driving.
Range of Performance
Because glandless pumps do not have any packing bush or internal bearing, full advantage can be taken of available drive speeds. The pump may be run at 1450 and 2900 RPM respectively and a range of impeller diameter for each pump size gives a wide spread of performance. In general the range cover flow up to 100m3/hr. and discharge head up to 50 meters. |
The Salient Features of Vertical Glandless Pump: |
- No mechanical seal, stuffing box and internal bearing provided
- No maintenance as this PP pump can even run dry forever as there is no seal, stuffing box and internal bearing
- The reduction of downtime prevents the production losses
- All the wet end parts of this polypropylene pump are molded construction that prevents failure caused by the corrosion and erosion
- The impeller is semi-open type used in our all-vertical pumps to suit both clear and polluted fluids.
- PP pump mounted outside the suction tank and is not submerged type
