SLURRY PUMPS

		The LPT Group range of horizontal spindle, centrifugal slurry pumps are ruggedly designed for the most arduous duties.

		Field-proven abrasion and corrosion-resistant rubber liners modled over steel reinforcement give maximum wear life. Alternative rubber compounds available for pumping oil, chemicals, food products, and higher temperature slurries. Bolt in design facilitates simple site replacement.

		Three unique Gland configurations are available: · Dry Gland – Unlike conventional mechanical seals, the dry gland has a stationary hard wearing face flexibly held against a rubber rotating ring. Any particle getting between the faces is absorbed into the ruber. This seal absorbs little energy and requires no external lubrication. The most popular gland option, it is particularly recommended where the use of gland water is undesirable.

		· Hydrostatic Gland – With loweset maintenance and longest life, the unique rubber gland seal is designed to deflect inwards to provide an effective seal. A clean water supply of 3-5 PSI above pump discharge is required with a flow of between 1/2 to 2 1/2 GPM depending on pump size.

		· Packed Gland – Sealing is obtained by compressing the gland packing rings onto the shaft sleeve. The gland offers the capacity to seal the pump even at high pressures, for instance in series pumping. A clean water feed or grease is essential to lubricate the packing to sleeve interface to provide additional cooling.

		Total Service From design through installation, LPT is ready to engineer a solution for your slurry pumping needs or problems. Whether it is a new installation or evaluation of an existing one, our experienced sales and engineering staff can assist with the right advice. LPT uses only the most experienced personnel to assemble the pumps, they are shipped only after passing our multi-point QA/QC program. A complete history is maintained on every Pump so you get the right advice the first time.

Pumptec: Computer Aided Support To complement and facilitate optimum selection of your slurry system, LPT uses “Pumptec”. This proprietary computer program calculates: Effects of changing slurry density Particle size P₅₀ from a sieve analysis Settling velocities and pipe sizes Pipeline frictional losses in various pipe materials and pipe fittings Pump and drive configurations based on input parameters Pumptec prints out full application and selection data sheets including NPSH, BEP, RPM, HP, etc. Troubleshooting is made easier using Pumptec to evaluate different scenarios.

Applications Sand plants Feeding sand and water to all types of classification and dewatering plants; effluent water transfer duties. Coal preparation plants For dense medium circuits; feeding hydrocyclones; filtrate pumping; handling the underflow from thickeners; disposal of effluent, etc. Chemical manufacturing & Environmental applications LPT pumps, by virtue of their various rubber linings, are suitable for pumping many chemical solutions, acid or alkaline, at moderate temperatures and for the disposal of effluent.
