MUNSCH CHEMICAL PUMPS IN CANADA
Corrosive Process Fluid Solutions Built for Maximum Plant Uptime
Flowstar supplies MUNSCH non-metallic chemical pumps for corrosive, abrasive and hazardous process applications. With mechanical-seal and seal-less magnetic-drive technologies, MUNSCH pumps help reduce corrosion, leakage risk and unplanned downtime in demanding chemical service.
MUNSCH NPC+ Chemical Process 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
When We’d Recommend It:
A strong choice for corrosive or abrasive chemical service where mechanical-seal technology, solids-handling capability and straightforward field serviceability are priorities.
MUNSCH CM+ Magnetic Drive 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
When We’d Recommend It:
Consider the CM+ when containment is a primary concern and eliminating the dynamic mechanical seal can help reduce leakage risk in hazardous or environmentally sensitive chemical service.
WHY MUNSCH
Built Around Demanding Chemical Service
MUNSCH specializes in non-metallic pump technology for corrosive, abrasive and hazardous process fluids. With multiple thermoplastic materials, mechanical-seal and seal-less designs, and configurations for demanding chemical service, MUNSCH gives Flowstar the flexibility to match pump technology to the fluid and operating conditions.
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.
Mechanical Seal or Magnetic Drive?
Both technologies can handle aggressive chemical service, but containment requirements, solids content, maintenance preferences and operating conditions can make one configuration more appropriate than the other.
| 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
Thermoplastic Materials for Corrosive Chemical Service
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.
Chemical Applications for MUNSCH Pumps
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.

Answers to Common Munsch Pump Questions and Performance Issues
High resistance allowing the pump to handle corrosive medium at varying temperatures and concentrations without any pitting taking place, like when using metallic pumps
Yes, we have suitable materials with increased mechanical resistance, approved over decades which can outperform even high alloyed metals, in use for solid contents of up to 30%,
Yes, we have different setups available
Yes, we can include:
- Single- or double acting mechanical seal arrangements + support system
- Several flushing methods for the sealing arrangement
- 4 different plastic materials, Polypropylene, Polyethylene, PVDF and PFA
- Magnetic driven pumps for clean liquids
Munsch does not only supply a rigid design of the mechanical seal, but also additional options, for flushing or quenching. Our dedicated engineering team will select the correct sealing arrangement , but also the most suitable method to operate it
By selecting the magnetic driven arrangements available, or a double acting mechanical seal with a thermosyphon system
In case the pump material in use does face any trouble with chemical attack, or something called erosion corrosion, when you do see chemical attack in combination with mechanical attack.
