Model 3-4CRM By Pedrollo
The Pedrollo 3 or 4 CRm multi-stage centrifugal pumps are quiet and as such these pumps are widely used in domestic applications such as the distribution of water in combination with small and medium sized pressure tanks, and for the irrigation of gardens and orchards.
Typically ships within 1 to 2 business days
Suitable for use with clean water that does not contain abrasive particles and liquids that are not chemically aggressive towards the materials from which the pump is made. The pump should be installed in an enclosed environment or sheltered from inclement weather.
