Non-Metallic chemical pumps engineered for hazardous, abrasive, and highly corrosive applications.
Corrosive Process Fluid Solutions Built for Maximum Plant Uptime
Flowstar is your Canadian resource for MUNSCH Pumps, offering mechanical seal and seal-less magnetic drive technologies that eliminate chemical leakage and unplanned downtime. Industrial facilities, chemical processors, and municipal water plants across Newfoundland and Labrador, New Brunswick, and Nova Scotia rely on Munsch’s heavy-duty polymer construction for uncompromised safety and long-term reliability in the toughest process environments.
Corrosion
Resistance
Thermoplastic construction helps solve corrosion challenges common with metallic pumps.
Technology
Choice
Mechanical seal and seal-less magnetic drive options allow the pump to match the risk profile.
Lifecycle
Focus
Clean-out and maintenance features support faster inspection and reduced downtime.
Engineered
Selection
Material, seal type, hydraulic selection, and temperature limits all matter in chemical service.
NPC+ Standardized Chemical Pump
The NPC+ is MUNSCH’s primary mechanical seal chemical process pump for corrosive and abrasive applications where serviceability, efficiency, and robust thermoplastic construction are required.
- Proven mechanical seal technology
- Strong field serviceability
- Well suited for many solids-bearing and corrosive fluids
- Available in multiple thermoplastic materials
- ISO-style standardized process pump concept
Resources
CM+ Standardized Chemical Pump
The CM+ eliminates the dynamic mechanical seal entirely through magnetic drive technology, providing enhanced containment for hazardous, aggressive, or environmentally sensitive fluids.
- No dynamic mechanical seal
- Designed for leak prevention and containment
- Reduced emissions risk
- Strong option for hazardous chemical service
- Thermoplastic construction for corrosive applications
Resources
| Consideration | NPC+ Mechanical Seal | CM+ Seal-less Mag Drive |
|---|---|---|
| Primary advantage | Serviceability and flexibility | Leak prevention and containment |
| Dynamic seal | Yes | No |
| Maintenance | Seal maintenance required | Reduced seal-related maintenance |
| Hazardous chemicals | Good to excellent | Excellent |
| Solids-bearing fluids | Often a strong fit | Application dependent |
| Environmental containment | Very good | Excellent |
Material Selection Matters
Chemical compatibility is often the first step in a successful pump selection.
PP
General chemical service and many common corrosive fluids.
PE-UHMW
Abrasive and corrosive services where wear resistance matters.
PVDF
Higher temperature and more aggressive chemical applications.
PTFE / PFA
Aggressive chemical services requiring premium resistance.
Typical Chemical Services
Final selection depends on concentration, temperature, solids content, and operating conditions.
Sulfuric Acid
Material review required by concentration and temperature.
Hydrochloric Acid
Common corrosive service requiring proper thermoplastic selection.
Sodium Hypochlorite
Often requires careful material and seal technology review.
Ferric Chloride
Highly corrosive; check material compatibility before use.
Process Chemicals
Flowstar can assist with application specific review.
Scrubber Liquids
Often corrosive and solids-bearing; selection depends on service.
Plating Solutions
Common in metal finishing and surface treatment systems.
Caustic Soda
Material choice depends on temperature and concentration.
