• MCP Series - Armored Plastic Mag Drive Pumps
• MCH Series - Machined Plastic Mag Drive Pumps
• MC-SP Series - Machined Plastic Self-Priming Mag Drive Pumps
• M Series - Injection Molded Plastic Mag Drive Pumps

Like lined centrifugal pumps, the volute of the MCP Series of end suction centrifugal pumps is protected by cast iron armor. Unlike lined pumps that are rotationally molded with plastic wall thicknesses of 1/4", the MCP Series is machined from solid plastic with wall thicknesses up to 3/4". Permeability through these thicker walls is non-existent.

The MCP Series is contructed with a dual rear casing. The outer shell is reinforced with carbon fibers for added strength. This design affords additional protection against over-pressurization.

Dimensionally built to ANSI B73.1 specifications for interchangeability, these pumps permit back pull-out disassembly.

MCP pumps are available in PVDF construction.

The standard material of construction of the MCP Series is PVDF (A Fluoropolymer)

Materials of construction for the Polypropylene pump are as follows:

MCH Series - Machined Thermoplastic Mag Drive Centrifugal Pumps

Unlike typical injection molded mag drive centrifugal pumps, the MCH Series is machined from solid bar stock. This enables obtaining wall thicknesses that are much greater than injection molded pumps, with thicknesses approaching 3/4". The rugged design of these pumps permits flowrates ranging over 450 GPM and heads over 180'.

Integral 150# ANSI configured flanges are available on all sizes, while NPT threaded ports are also featured on the smaller models.

MCH Series pumps are available in polypropylene and PVDF (A Fluoropolymer) construction.

MC-SP Series - Machined Thermoplastic Self-Priming Mag Drive Centrifugal Pumps

The MC-SP Series share the same basic features and materials of construction as the MCH pumps, with the addition of a self-contained, self-priming pump casing. No longer is flooded suctiion necessary to start up a centrifugal pump.

M Series - Injection Molded Plastic Mag Drive Pumps

M Series pumps are designed to be more rugged than other injection molded pumps. Thicker wall construction reduced the need for ribbing required in competitive pumps and improves chemical resistance. A larger diameter shaft reduces bending stresses. The oversized thrust washer minimizes wear from axial loading.

Competition                M Series

M Series pumps utilize a modular construction for the impeller and magnet assembly. If the impeller (less expensive component) is damaged, a new impeller can be reassembled to the existing magnet. With a unitized construction found in most competitive models, the entire assembly is replaced, even though the magnet is sound.

M Series pumps mount to standard NEMA C FACE motors, including UL recognized explosion proof motors. Optional high torque magnet couplings permit pumping higher specific gravity liquids than competitive pumps allow.

M Series pumps are available in Polypropylene and PVDF (A Fluoropolymer) construction.
