Calpeda Self Priming Pump 4kw, 5.5hp

The option to choose between cast iron and bronze materials for the hydraulic parts in contact with the pumped liquid allows NMP series pumps to be selected for use with different types of liquids.

A large capacity Stainless steel filter is fitted which is easy to remove for inspection and cleaning.

An innovative, patented guard prevents contact with rotating parts, proving protection to the end user whilst allowing for inspection of the mechanical seal.

The bearing and shaft are designed to ensure the reduction of the stress, providing high reliability under all operating conditions.
