PUMPS

 

All wetted parts of these pumps are pressure cast in solid construction in PE-UHMW the versatile engineering thermoplastic exhibiting superior properties such as self lubricating, very low coefficient of friction, almost zero moisture absorption, fatigue resistance, excellent chemical and corrosion resistance, light weight, wide service temperature capability from -270 deg.C to 90 deg.C. Vertical Glandless Pumps run completely dry without ill effect are used in applications requiring the continuous transfer of liquids, with high degree of reliability, hence remove one cause of breakdown which is often attributable to the human element. The most important gains to be derived from the use of glandless pumps are in the sphere of maintenance and the consequent reduction in down-time production losses. Normal maintenance on the Vertical Glandless Pumps is confined to lubrication of the driving motor bearings.

Some of Its Typical Applications to Date

• H3PO₄, 18% -24% H2SiF₆ with 5%-7% siIica,H2SO₄, HF and their mixtures with or without solid (Gypsum) up to 40% conc
• Replaces HV-9A, Alloy-20 & Si-iron. Chlorinated Brine, Conc. HCI, 60%-7O%H2SO₄ at 800C• Scrubbed liquids containing F, CI, SO₂, Ammonia gases etc. with solids. Replaces Hastelloy
• Spin Bath Solutions (H2SO₄, ZnSO₄, Na2SO₄ etc.)
• Carbide Sludge with Sand, 40% TiO₂ Slurry, Alcohol with 5% Gypsum Slurry etc, Acidic effluents sludge containing cell brine, phosphoric acid Sand and Phosphates
• Other applications are in Metal Refineries, Pickling Installations, Paper & Fertilizer Plants, Cement Plants, Sugar plants

 

Range of Performance

Because Vertical Glandless Pumps do not have any packing, bushes or internal bearings, full advantage can be taken of available drive speed. The pump can run at 1450 and 2900 RPM. Respectively and a range of impeller diameters for each pump size gives a wide spread of performance. In general the range covers flows up to 5OOM3/hr. and discharge up to 60 meters.

Applications of PE-UHMW Material in other Industries
