Retrofit Pumps - WMC-U Series
- Solid Non-Metallic Seal-less Retrofit Mag-Drive Pumps:

Warrender specializes in highly engineered seal-less magnetically driven process pumps to safely meet corrosive process requirements and meet EPA Zero (0) Emissions.
Warrender WMC-U0, U1, 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.

Cornell & Buffalo Retrofit Pump solutions are also available.

Warrender’s 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.

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

Commerical Benefits:

• Eliminates costly and complex mechanical seal systems
• Avoidance of mechanical seals that cause production downtime
• Zero leakage, magnetic coupling circumvents constant EPA monitoring and potential fines from excessive emissions associated with mechanical seals
• Efficient hydraulic design minimizes power consumption
• Magnetic coupling prevents the introduction of unwanted air into the process for higher production yields
• Positive sealing with integral flanged ports eliminates the chance of emissions from plastic threads
• Simplified maintenance, with registered fits, requires no special tools or settings
• SOLID thermoplastic casings never corrode (internally or externally)
• Premium machined pure thermoplastics provide higher resistance to chemical and temperature degradation than molded or composite materials
• Standard NEMA motor frame allows for low cost, fast replacements in the field
