SSI-50DMC Double Cartridge seals are self-contained units consisting of a

shaft sleeve, seal, and gland plate. The unit is fitted onto the

pump shaft as a built assembly, and no further fitting is

required. Double Cartridge seals are an attempt to over-come the

fitting problems of conventional seal, They are supplied in

double form, and the gland plate is often fitted

with various tapping to provide for flushing, cooling water

injection, and disaster control.

DOUBLE Cartridge Seal :  We are providing our customers a wide range of Double Cartridge Seals. These cartridge seals are widely finds its applications in various industrial sectors.

SSI-50DMC Double Cartridge seals are self-contained units consisting of a shaft sleeve, seal, and gland plate. The unit is fitted onto the pump shaft as a built assembly, and no further fitting is required.  Double Cartridge seals are an attempt to over-come the fitting problems of conventional seal, They are supplied in double form, and the gland plate is often fitted with various tapping to provide for flushing, cooling water injection, and disaster control.

The cartridge can overcome several limitations of the standard pump gland. Tangential tapping for introducing fluids into the gland cause less  disturbance to the seal face than the radial tapping often found on pump units. Look again at the tapping provided for flush water to the packed gland, a tangential tapping would provide a less turbulent water source. For a packing gland this may not be important but to a mechanical seal it can be another adverse condition with which to cope.

The setting position of the seal is set by the cartridge design, but the seal unit should not be screwed to the shaft until the gland plate is secured to the pump and any adjustments made to the shaft position. Once this has been completed the set screws can be tightened and the spacers removed.

So, what can go wrong. The design works to eliminate many of the common causes of seal failure on installation and because the seal is presented on its own shaft sleeve any damage that might be caused by a conventional seal to the pump unit is also eliminated.

Operating Condition:

• Shaft Dia. : 25 to 150mm
• Pressure :up to 15 Bars
• Temp. : -50 to 180°C

Single Cartridge Seal solutions 

Sam Seals India brings reliable Single Cartridge Seal solutions designed to simplify installation, reduce leakage risk, and improve pump performance in demanding industrial conditions. A cartridge seal is a complete, pre-assembled sealing unit that includes sealing faces, gland plate, sleeve, and other key components—so your maintenance team can fit it faster with fewer chances of alignment errors. This makes it ideal for plants that want consistent sealing, minimal downtime, and predictable operating life.

Single cartridge seals help control product loss, prevent contamination, and support safer operations in pumps handling water, chemicals, light hydrocarbons, and process fluids. They are commonly used in industries such as chemical processing, pharmaceuticals, food & beverage, paper, textile, and general manufacturing where reliability and clean running are critical. With stable sealing performance, they also help protect bearings and reduce vibration-related issues that often come from poor sealing setups.

Sam Seals India focuses on practical sealing solutions that match real operating conditions—pressure, temperature, shaft size, speed, and media compatibility. Whether you need a standard configuration or a customized option, our team helps you choose the right seal arrangement and materials to achieve long-term efficiency.

Single Cartridge Seal Applications Overview

Single cartridge seals are widely used in centrifugal pumps, mixers, and rotating equipment where quick replacement, reduced setup time, and dependable sealing are required—especially in continuous-duty and maintenance-sensitive environments.

TYPE SSI-55 Single Cartridge Seal Series is a modular cartridge seal family that includes elastomer o-ring pusher seal designs. Type SSI-55 single seal arrangements incorporate an elastomer o-ring as the secondary sealing member. A common seal head/mating ring set, utilized throughout all versions, is reversible to allow rotating. Seat/mating ring or rotating seal head operation, and is interchangeable with metal bellows seal heads. Seal has an optional quench gland with carbon ring throttle bushing.

Balance Pusher Seals available in Single Configuration used for Sealing Environmentally. Dual Directional. Stationary spring design. Reversible Seal Head. No clogging Wave Spring outside the Product. Components in Cartridge Design are Builds for the Highest Reliability and Simple Installation.
