HMD Kontro CSA/CSI Chemical Service Pump

Sundyne HMD Kontro Magnetic Drive Pump Models CSA CSI

Leading Sealless Pump Performance for the Chemical Industry

The CSA / CSI is HMD Kontro’s newest range of chemical service sealless pumps with full compliance to ASME B73.3 and ISO 2858 / 15783 standards. Incorporating latest magnetic drive technology, the range features a simple, modular design with maximised interchangeability, high efficiency hydraulics and a number of upgrade options to ensure suitability with a wide range of applications.

The CSA / CSI range features different hydraulic sizes that conform to current ASME / ISO dimensional, performance and construction requirements. Close-coupled and separately mounted variants are available along with a wide range of options including secondary control or containment, instrumentation and various bearing isolation and lubrication options. The range is specifically designed for maximum part interchangeability, ease of onsite service and has a wide number of site upgradable features.

Key Design Features

Sealless Design: For total product containment, essential for hazardous, aggressive or valuable liquids
No Seals: Minimises maintenance and all of the associated costs, and eliminates potential leak paths
Modular Construction: With interchangeable components for maximum design coverage, reduced inventory needs and minimised lead times
High Efficiency Design: Providing reduced power consumption through optimised hydraulics and the Zeroloss Containment Shell option.
Site Serviceable Design: Facilitating ease of on-site maintenance activities with removable wear rings, simplified internal bearing replacement with no hot working required, bearing housing oil overfill protection and no requirements for special tools.
Robust Design: Featuring a single fully confined casing gasket, internal and external bump rings, and the Zeroloss containment shell option for increased tolerance to system upsets.
Secondary Control and Containment available as upgrade options across entire CSA / CSI and can be installed in both Close-Coupled and Separately Mounted configurations
