KSB introduces “easy to install” 4STQ mechanical seal cartridges

Dec. 13, 2016 – KSB Pumps has introduced a new family of modular cartridge-type mechanical seals which it says are optimized for wet or dry-installed wastewater pumps.

Two seal stages are arranged in tandem and boast “highly wear-resistant” silicon carbide primary rings to ensure “excellent” protection for the pump’s bearings and motor and “long, trouble-free service lives.” The 4STQ modular seals are designed for KSB’s Sewatec and Amarex wastewater pumps and are suitable for the full range of operating conditions specified for these pumps, says KSB. The modular design of the seals promise to minimize downtime during maintenance, says the company, adding that it prevents the seals from being installed incorrectly. As well, there is no need for assembly fixtures or fastening bolts. All metal components are manufactured from corrosion-resistant stainless steel while FKM elastomers are used for the O-rings.
