Linapump IIIr Selection
The importance of selecting the correct size and type of Linatex slurry pump cannot be overstated. Selection is based on analysing a number of factors which, when considered in total, determine the pump’s performance for a given installation and duty.
‘D’ - Dry Gland : Unlike conventional mechanical seals, the Linatex dry gland has a stationary hard wearing face flexibly held against the Linatex rubber rotating ring. Any particle getting between the faces is absorbed into the Linatex rubber. This seal absorbs little energy and requires no external lubrication. It is particularly recommended where the use of gland water is undesirable.
‘H’ - Hydrostatic Gland : With lowest maintenance and longest life, the unique Linatex rubber gland seal is designed to deflect inwards to provide an effective seal. A clean water supply of 0.2 bar above the pump discharge pressure is required with a flow of between 0.04 and 0.15 liters per second, depending on pump size.
‘P’ - 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.
