Manufacturing capacity

For today capital repair of the additional production building with total area of 1195m² has been performed within the framework of the Company's development strategy. Welding area, mechanical area for machining of DGS body and rotor parts, control panels assembling and testing area have been set in this building, balancing machine was mounted and upgrade of DGS assembling facilities and DGS test rig was executed.

When fulfilling the program of production development LLC John Crane – Iskra is striving for manufacturing high-quality Russian-made products at fair and economical price, which can be competitive both in domestic and foreign markets.

Mechanical area
Production of metal parts for the following products is carried out within the mechanical area: DGS control panels, components for DGS control panels, couplings parts, etc. It is equipped with turning, milling and coordinate boring machines, as well as with auxiliary equipment and tooling necessary for manufacture of quality products. Machines are operated by highly qualified staff personnel.
Welding production
Welding area is located in the production building. Parts and pipelines welding is perfromed there. Manual argon-arc welding is provided with all the required certificates and NAKS (National Agency of Non-Destructive Testing and Welding) permits. Production capacities of the welding area make it possible to manufacture frame parts and pipelines for different types of CP using our own efforts .
Balancing area
Balancing of DGS rotor parts and couplings parts is performed in the balancing area. The machine lift capacity and accuracy provide balancing at set parameters for all DGS and couplings of standard sizes.
Oven and seal head test rig for polymers heating and fitting
There are oven for polymer seals heating and seal head tester. The oven is designed for heating and pressing polymers into their fitting areas. The test rig is used for testing face pressure force.
Control panels assembling and testing area
CP assembling and testing are carried out in the appropriate area of the production building. The area is equipped with the equipment required for CP production within the shortest time possible. Proper area equipment make it possible to produce CP of different standard sizes and parameters as well as to perform CP pressure tests at over 1000 atm.
Measuring unit
Up-to-date high-precision instrument designed for roundness and surface finish check of parts. It is required for interoperational inspection during assembling process of such new DGS types as Aura™.Aura™.
Faces lapping and polishing area
Faces manufacture and refurbishment take place in the lapping and polishing area. Existing machines ensure necessary shape for face working surface. The area is also equipped with optic flat system for surface condition control.
Test rig for seals dynamic testing
Provides an opportunity for static and dynamic testing of new and refurbished DGS. The rig parameters make it possible to run tests at high pressures and speeds. The test rig software provides recording of the tests performed and monitoring of all the operation parameters of the rig and DGS.
Large stock of products spare parts
In case if long-term servicing contracts are signed with customers LLC John Crane-Iskra arranges stocking of spare parts within its premises. This service provides an opportunity for prompt refurbishment in case of seal failure which significantly improves refurbishment lead time and ensures equipment idle time.
