Calpeda NMP is a self-priming pump that does not require filling the inlet pipe with liquid before starting. This method of operation simplifies the use of the unit, thereby reducing labor costs for operation. The NMP monoblock centrifugal pump is equipped with a cleaning filter that pre-cleans the incoming liquid when starting the pump. The pumps are used to pump clean (drinking) and contaminated (technical) water. These pumps are widely used in the field of cleaning and filtering swimming pools.
