Spare Kits to Maximise the Uptime of Your Sealless Pumps

The Aftersales engineering team at HMD Kontro Sealless Pumps has comprehensively analysed typical service procedures, maintenance requirements and common repairs to create a portfolio of spares kits that can be held at your installation or at HMD Kontro’s regional hubs for quick and easy servicing and repair of pumps onsite.  These include:

Service Kit – Contains bearings, gaskets, and O-rings for planned maintenance procedures.

Commissioning Kit – Consists of spare gaskets and O-rings that may be needed during the commissioning of a new installation.

Cartridge Kit – A drop-in cartridge containing all the wetted sealless pump parts, which just slots in without the need for a skilled operative.

CS Magnetic Torque Ring Upgrade


The upgrade of the outer magnet ring on the CS pump range offers significant advances in magnetic coupling robustness leading to increased MTBF (mean time between failure), reduced downtime / increased uptime and increased operational efficiency.


The retro-fittable outer magnet ring (OMR) provides shielded magnets that retain the same level of performance and eliminate any potential for damage.  The new OMR has improved cyclic thermal duty whilst the identical coupling power produced means that the upgrade maintains similar performance to maintain reliability.


The encapsulated magnets on the OMR are made of samarium cobalt and have increased resistance in corrosive applications.  They also provide higher efficiency by reducing slip and improved reliability because no tie bolts are used in the retention of the magnets.


This upgrade is straightforward as no specialist tools are required and is recommended as the current magnets used in the CS pump are becoming obsolete and so no longer available as spare parts.


With increased safety due to there no longer being a remote possibility for the magnets to come into contact with the containment shell, this upgrade is recommended for all current CS pumps.
