About C•Shell Pumps

Generated from efficiency. Adapted for flow. Built for longevity.

The C•Shell pump series is MDM’s new horizontal centrifugal lines product family designed for use in the Chemical Process Industry (CPI) and other corrosive fluid handling markets. C-Shell products are a complement to MDM’s larger line of non-metallic, end-suction centrifugal pumps. They’re armored pumps consisting of metallic cast pump shells with a thermoset polymer non-metallic lining. As with MDM’s non-metallic Genesys and Advance products, C-Shell products have been designed to offer the highest efficiencies, lowest maintenance cost and longest life – for the lowest total cost of ownership. Oversized volutes offer high flows at low rotational speeds for nearly silent operation.

Mechanical seals are a Type 21 cartridge, offered in a wide range of seal materials compatible with different pumped fluids.  The seal chamber design provides for easy and fast installation.

Use of proprietary pump selection software enables MDM to tailor pump solutions to each system requirement, assuring optimum efficiency and highest return on investment for MDM customers.

Why C•Shell?

Process pumps are a significant investment in every application.  The business environment of today is dominated by conglomerates with offshore production no longer driven by total cost of ownership but intensely motivated by high margin repeatable component sales.  MDM has remained an independent family owned business whose core values are built into every pump – a high level of integrity and commitment to service life that offers the lowest total cost of ownership.

The C•Shell product line is an extension of this very philosophy that has kept MDM ahead of its competitors for over 40 years.  The innovative ultra-strong yet thin vane design of our Edge impeller technology provides high flows and pressure in a compact design.  The armored FRP internals and ductile iron cases allow for highest corrosion and temperature resistance.  The C•Shell pump series has a vast range of value that should be considered for your next project.
