Pump manufacturer installs bushings with ease

Argentina – A global company dedicated to the manufacture, sales and service of fluid-handling equipment has commented on the ease with which it installed a total of 12 Vesconite Hilube line-shaft bushings and two Vesconite Hilube stuffing box bushings in two 18-m-length pumps.

The bushings were 300mm long but, after two hours in dry ice, the pump manufacturer fitted the bushings by hand without any help.

Because thermoplastics harden and soften with temperature, freeze fitting is particularly useful when installing large polymer bushings, bushings with thin walls, or bushings where the length is greater than the shaft diameter.

More efficient pumps easily achieved with new Vesconite Hilube wear rings

Independent tests by a major pump manufacturer prove corrosion-free Vesconite Hilube wear rings safely allow reduced running clearances and improve pump efficiency.

Unbeatable bearings

APE Pumps, a pump supplier to many countries, including Zambia, Iraq and South Africa, replaced every pump bushing that it was able to with Vesconite. The company had tried many different types of bushings but was impressed with Vesconite’s toughness, long-life and self-lubricating qualities.

Vesconite Hitemp 150 for condensates

When a large energy company in Africa required lineshaft and bowl bearings for condensate pumps at its 4,000 MW power station, it turned to Hitemp 150, an engineered polymer produced by Vesconite Bearings, that can survive temperatures up to 150°C (300°F). The condensate pumps in question reach temperatures of 110°C (230°F), so the contractor to the power producer is satisfied that the pumps will last and that the bearings will not melt, as would be the case with many other polymers.

Vesconite bushings ensure glue pump restarts successfully after down time

One of South Africa’s largest independent polyurethane and plastic foam manufacturers restarted an important gear pump, used to pump glue to rebound foam chips, without difficulty after the company’s December-January closed period. Not only that, the Vesconite Hilube pump bushings, which were inspected at the time of the restart, showed no wear.

Electricity cost saving on pumps fitted with Vesconite Hilube wear rings

A large pump original equipment manufacturer compared energy usage on a typical submersible pump when a Vesconite Hilube wear ring was in place and when a bronze wear ring had been installed. The results independently proved Vesconite Hilube’s ability to improve pumping efficiency and decrease electricity usage.

Vesconite Hitemp 150 pump bushings show no scratches after one year

When the team responsible for the maintenance of the irrigation system at one of South Africa’s premier golf courses was confronted with high levels of debris and pumps running dry for periods, it shifted to a high temperature resistant, high wear resistant polymer, Hitemp 150, for replacement pump bowl bushings. The bushings lasted a year without a scratch.

Vesconite Hilube performs in challenging Nile river conditions

A Turkish OEM that supplied a Nile River project with one of its pumps that had been fitted with Vesconite Hilube polymer components in late 2018 reports that the line shaft bushings continue to operate well. The project is associated with abrasive water with a large proportion of sand particulates for which hard-wearing Vesconite Hilube is ideal.
