Description
Standardized chemical pump ECM/ECM-B
The ECM-series pumps are used for the safe pumping of fluids posing an environmental or health hazard such as acids, alkalis, solvents and chemically contaminated fluids in the presence or in the absence of solids. Their hermetically sealed design makes them excellently suited to sensitive applications involving major hazards to humans and the environment. It is Constructed as an horizontal centrifugal pump, process pump design. With casing dimensions, fitting dimensions and design to EN 22858/ISO 2858/ISO 5199, complemented by size 40-25-125 and 40-25-160.
Advantages and characteristics
Numerically optimized hydraulics
The fluid dynamics of MUNSCH pumps are calculated, visualized and optimized using the latest numerical techniques (Computational Fluid Dynamics). The result is a hydraulic design with a virtually ideal flow profile.
This means:
- higher pump capacity at unchanged differential head
- reduced energy costs
- improved suction behaviour through low NPSH requirements
- minimized wear in abrasive service conditions
- reduced running noise
The pump adapts to the task at hand – impeller designs
MUNSCH has the right impeller design for your specific pumping application. Wear, suction behaviour and efficiency are key factors determining the choice of the impeller. The right combination of impeller (hydraulics), material and shaft seal is all-decisive for a successful pump design and long service lives. MUNSCH pumps are available with closed, semi-open and vortex impellers.
Reduced lifecycle cost
The numerically optimized hydraulic design is a key factor in minimizing the lifecycle costs of MUNSCH pumps. Capital and maintenance costs are reduced through the selection of the best suited hydraulic design and optimum motor sizes. Smaller cable cross-sections and lower-rated motor breakers keep down installation costs. The high pump efficiencies directly translate into energy savings.
Explosion protection as per EU Directive 94/9/EC as option
Additional engineering measures can be provided to allow the use of the pumps in explosion hazard zones. The pump meets the requirements of EU Directive 94/9/EC.
Solids-carrying fluids
A solids deflector in the pump casing redirects solids away from the mechanical seal and back to the flow path of the process fluid.
Pump characteristic
MUNSCH chemical pumps feature a steep performance characteristic. This means that the pumps can be adjusted exactly to the operating point.
Options
- Explosion protection as per EU Directive 94/9/EC
- Base plate
- Levelling bolts as an alternative to pump concrete pads
- Coupling with/without spacer sleeve
- Sturdy coupling guard
- Casing drain
- Priming pot
- Motor overload switch
