Mechanical seals - Import export

Cartridge mechanical seal single or double type, with our without flush, with our without lip seal. Seals are for application in demanding conditions such as pulp and paper industry, mining industry, various stages in the oil and gas industry, etc.

Sealing solutions for pumps, compressors and mixers. Single pusher mechanical seals for water pumps and simple application.

Rotary pressure joint is an assembly which secures sealing between inlet pipe and rotational cylinder thus providing heat transfer by media in or from the equipment's rotational element. Fluids that are commonly used for heat transfer are water, thermal oils, hydraulic oils, cooling fluids and vapor. When it comes to rotary pressure joints, sealing of work fluids is done by the use of mechanical seal. The mechanical seals spring provides contact between sealing faces before the machine starts it's work, while during work, the contact is secured by the act of hydraulic pressure, except in cases of low operating pressures or vacuum. The right choice of mechanical seal is of major importance in order to reach the work of rotary pressure joint efficient , because in cases of mechanical seal malfunction, leakage occurs which reduces efficiency of entire cooling or warming process. “ Kroma Ltd” delivers rotary pressure joints with either single or dual flow.

Cartridge mechanical seals manufactured to meet API 682 (ISO21049) are meant for use in the petroleum, natural gas and chemical industries. During processing of crude oil various chemical compounds are being released, and designers should count on sealing fluids which could be: -under the very high pressure -under very high or very low temperatures -on very high or low pH value -very high or very low viscosity -abrasive -harmful, polluting and potentially explosive API 682 (ISO21049) specifies requirements and gives recommendations for sealing systems with aim to secure that the fluids with characteristics above could be transported: -with minimum waste -with maximum environmental protection -with minimum mechanical failure -with best price-quality ratio
