Pluggable mechanical seals SPLITMIX for pumps and mixers

28 October 2019

We are pleased to introduce the new Kroma LTD - mechanical seal range - fully split mechanical seals for pumps and mixers.

Split mechanical seals SPLITBOX for pumps and SPLITMIX for mixers allow quick and easy installation of the seal on the shaft without completely disassembling the equipment, which significantly reduces downtime.


The use of detachable mechanical seals significantly reduces the level of leakage, compared with the stuffing box in the absence of wear of the shaft sleeve.

Seals are easy to install without adhesive!

Detachable mechanical seals are used where the complete disassembly of equipment is very long and time-consuming and it is important to minimize production downtime:

- pulp and paper industry;

- water treatment and sanitation;

- shipbuilding;

- heat power engineering;

- mine production.
