MKP – Stainless Steel Magnetic Drive Chemical Process Pump
Discover here the advantages of the MKP from CP – The highly reliable centrifugal pump for various applications.
Find out more about our MKP pump in our animation.
Overview
Special features
- Up to 30% solids concentration and 1 mm particle size can be pumped – depending on the nature of the particles*
Construction
- Unique drive and bearing concept
- Compact & virtually free of dead space
- Bearing frame & close-coupled design
- No shaft feedthrough & leak-free
- Low product content
- No plain bearing carrier, no rotating shaft
- Single-part & central bearing, on all sizes
- Horizontal & vertical installation possible
- Low bearing forces due to hydraulically balanced impeller
- Internal & external bearing lubrication options
- High material flexibility (casing, impeller as well as plain bearing materials)
- Eddy-current-free shroud possible (> reduced energy consumption)
- Inverted drive principle at flow rates up to approx. 200 m³/h
- Single-stage centrifugal pump
Heatability
- Single-part heating chamber system
- Very efficient heatability
- Only 1 entrance and 1 discharge connection
- Simple & easy to heat, a single heating jacket reduces installation costs
- Low temperature difference in the pump & no cold zones thanks to excellent heat distribution
- Short heating up time due to high thermal transfer efficiency & direct feed of the heating energy into the fluid space
Assembly & repair
- Modular system made up of few individual parts
- Assembly friendly
*In general, media with solids content can be transported, but application-specific verification in advance is necessary.
