Retrofit Pumps


Chemag® Retrofit Mag-Drive Pumps for Corrosive Processes

CHEMAG® specializes in highly engineered seal-less magnetically driven process pumps to safely meet corrosive process requirements and meet EPA Zero (0) Emissions. CHEMAG® CP-U0, CP-U1, CP-U4 are machined billet thermoplastic and fluoroplastic pump casings and components provide optimal resistance to corrosive chemicals. Non-metallic materials are subjected to rates of swelling and permeation that challenges molded designs with thin wall construction. Glass reinforcement alters the chemical resistance, leading to permeation, “wicking” and degradation.

Chemag® CP-U0 Retrofit Mag-Drive Pump

CHEMAG® CP-U Series pumps are fabricated from SOLID extruded pure PP or PVDF thermoplastics to resist internal or external corrosion. Heavy walled, CNC machined construction provides resistance to permeation and migration of corrosive, and aggressive liquids. CP-U Series pumps avoid deformation and degradation, with lesser designs, even in the most severe applications..

Pump Casings & Internal Components:
• Glass-Free Polypropylene (PP) or Polyvinylidene Fluoride (PVDF)
• Exclusive Heavy-Duty Rear Thrust Bearing
• Shaft & Casing Wear Ring: Silicon Carbide
• Internal Bearings: SIC or PTFE-C
• Casing O-Ring: EPDM, Viton or FEP

Technical Features:
• Exclusive SOLID machined PP or PVDF casings and impeller components for maximum
chemical resistance
• Robust casing wall thicknesses
• Solid thermoplastic casings withstand external corrosion
• Integral raised face flanges (no threaded adapters) for positive sealing and zero leakage
• Oversized, Casing wear rings & thrust bearings
• Modular impeller allows for varying hydraulic performances
• Compact, high torque magnetic coupling with reduced mass
• Zero leakage, magnetic coupling circumvents constant EPA monitoring
• Standardized NEMA or IEC motors
• Simplified maintenance, with registered fits, requires no special tools or settings

Chemag Molded Retrofit PP or PVDF Mag-Drive Pump Model CP-U4

More Info:
CHEMAG® non-metallic designs are uniquely constructed from pure Polypropylene (PP) or Polyvinylidene Fluoride (PVDF). Rugged pump casings and impeller assemblies are machined from solid extruded bar and block material. CNC machined construction provides distinctive advantages over molded or lined configurations. Typical casing wall thicknesses for molded pumps are only 1/8” - 1/4”; failures often result from chemical attack, thermal expansion and pipe stress. Lined pumps have a mere .100” - .120” lining thickness and the added risk of casing failures caused by separation permeation or external corrosion. Solid thermoplastic pump casings feature wall thicknesses of 1/2” to 1-1/2” for optimal chemical resistance and durability.
