With over 35 years of vertical pump bearings manufacturing experience. We manufacture pump cutlass bearings in all sizes and types for leading OEM’s, repair centres and distributors. GMP bearings are custom made to our client’s requirements to accommodate any size, materials and volume.

GMP Industrial water lubricated bearings are used for Vertical turbine pumps including axial flow and diagonal flow – Circulating water pump, auxiliary refrigerating seawater pump installed in nuclear power plants, thermal power plants, desalination plants and lift irrigation projects, city/town municipal water projects and waste water treatment plants.

Speciality Rubber Compounds

GMP engineers can develop industrial rubber compounds that are specially engineered to meet the performance requirements for your applications.

Bond Strength

Industry leading rubber to metal shell bond and rubber to composite shell bonding techniques developed by GMP ensure fails safe bonding of rubber-to-metal and rubber-to-composite. GMP bearings have industry leading bond strength of 235 PSI (16.5 Kg/sq. cm)

Concentricity and Cylindricity

Most manufacturers use centreless grinding techniques to finish the outside diameter but centreless grinding process does not take the inside diameter of the bearing into account, the centres of the outside diameter and inside diameter may not be the same.

GMP bearings are mounted on a mandrel and ground on a cylindrical grinder, thus achieving better concentricity as well as cylindricity to the full length of the bearing so that it is perfectly circular, perfectly straight and has no taper, as compared to bearings turned on a lathe machine.

Tight Tolerances

GMP Industrial water lubricated bearings are custom machined to meet exact specifications of our clients for clearance and tolerance.

Energy Saving

GMP rubber bearings have very low coefficient of friction, when compared with any other bearings. The low coefficient of GMP bearings help in reducing friction and thus cut energy losses.

Protect shaft and Sleeve

The inner groove design of GMP bearings combined with proprietary rubber compound creates a hydrodynamic lubricating film even at low shaft rpm. The grooves are designed for maximum lubricating water flow and dissipation of frictional heat. Abrasive grit is flushed out through these grooves, protecting the shaft/sleeve as well as the bearings from damage.

Vibration Absorption

GMP proprietary rubber compound is more durable against friction when compared with other rigid bearings. Furthermore, GMP rubber bearings have higher ability to suppress vibrations from the shaft, thus running silently.
