Velmake Seals Goregaon, Mumbai, Maharashtra

Type VMH - 21 is a compact cartridgised balanced seal specially developed for handling slurries, sludges, thick syrups and polymerising fluids. In the cartridge construction the springs are isolated from the fluid enhancing the seal life. After detaching of the location plates provided, the seal can be easily installed straight away without setting measurements. Series 50B is a sturdy robust, seal capable of maintenance free runs for years together.     Seal Characteristics   Single Seal Balanced Independent on direction of rotation Cartridge Unit     Application   Pulp & Paper Slurry Pumps Sludge Pumps

Type VSS -SPL is single coil spring seal developed for light contamination, dirty media and clogging type application. This type also allows it to fit onto a normal shaft without any balancing step. The mechanical drive of this seal is realised by grub screw which lock onto the shaft. The seal has a limited axial length, compact shape which allows easy mounting.     Seal Characteristics   Single Seal Unbalanced Helical Coil spring Independent of direction of rotation     Application   General Chemicals Petrochemicals Light Hydrocarbons

Type VS - 2 is unbalanced single acting helical coil spring seals independent o1 direction of rotation. The drive ring's notch design eliminates over stressing of the elastomer bellows. Slippages are eliminated, protecting the shaft and sleeve from fretting. Seal can be repaired in field with minimum spares, minimizing the downtime cost.     Seal Characteristics   Single Seal Unbalanced Conical spring Independent of direction of rotation     Application   Water pumps,Oil pumps Blowers Compressors Slurry pumps     Performance Range

Shaft Diameter : 10...100 mm

Pressure : 22 bar (max

Metal Parts : SS304, SS316

Type VT- 9 / VT - 9W are multi spring, pusher type unbalanced seals used for universal applications. The seals are compact in design suiting all types of rotating equipments, pumps and mixers. Drive lugs in the retainer will provide torque transmission and reduce slippage on shaft and sleeve. A snap ring holds all components together, helping in easy installation. The parts are interchangeable, VT- 9 can be converted to VT - 9W by just changing the seal ring and the secondary member.     Seal Characteristics   Single Seal unbalanced Independent of directions of rotation     Application   General Chemicals Petrochemicals · Refineries Light hydrocarbons, Water     Performance Range

Shaft Diameter : 18...100mm

Pressure : 10 bar (max)

Type VMB - 50G seals specially designed for high temperature application and suitable for high start-up toque since the bellows unit is independent of torque transmission. Grafoil is used as a secondary member having excellent temperature range upto 4000C. Shrunk fit seal face design minimize face distortion restricting leakage and wear rate to very low level under a wide range of condition.         Seal Characteristics   Single Seal Balanced Metal Bellows Independent of directions of rotation     Application   High temperature applications Petrochemicals Refineries

Shaft Diameter : 18...100mm

Pressure : 20 bar (max)

Temperature : -20...4000C

Type VC - 108B mechanical seals are designed for heavy duty service involving high pressure and sliding velocities. This seal has positive drive arrangement and sturdy construction making the seal suitable for high pressure application. Multiple spring design provides uniform face loading. The seal is supplied as a cartridge unit and can be directly bolted to stuffing box. These seals are normally used in main oil pipelines, water injection pumps and boiler feed water pumps.     Seal Characteristics   Single Seal Balanced Independent of direction of rotation   Application   Main Oil Pipeline Water Injection Pumps Boiler Feed Water Pumps

Pressure : 80 bar (max)

Type VBSM - 3 is single conical spring, unbalanced seal with O-ring provided for secondary sealing. Since the Torque transmission is done by the single coil springs the seals are dependent on the directions of rotation, which is seen from the drive end of the shaft. Right handed spring and left handed springs are provided for clockwise and anticlockwise rotating shafts respectively. These seals can carry a variety of seals faces, serving application in submersible, sewage, chemical transfer, water pumps etc.     Seal Characteristics   Single Seal Unbalanced Conical spring Dependent on directions of rotation   Application   Water pumps Submersible pump Sewage pump

Type VTC - 12 is the balanced seal without need for step sleeve. This seals are designed for media containing solids or with high viscosity. The springs are protected from media, thus no clogging of springs or springs compartment, resulting in high reliability.     Seal Characteristics   Single Seal Balanced Capsulated Spring Independent of direction of rotation     Application   General Chemicals Food Industries Media Containing Solids

Seal Faces : Carbon, SiC, Tung. Carbide

Type VCB - SHC1 are preset factory assembled cartridge seals for use in Agitators, Mixers and Reactor Vessels. The seal construction varies slightly for top entry vessels, side entry vessels and bottom entry vessels. The seals are designed to the shortest shaft length and the bearings are located as close to the vessel body to minimize the deflection.
