1" Diaphram Pump Metal Housing

The DDP25 offers an economical fluid transfer option where medium to high flow rates are needed with little back-pressure. The ability to dry-run allows easy priming while operating without any damage to the pump. A removable air valve offers repairs to be made while the pump is still fitted in place for quick simple maintenance. The Polypropylene / Aluminium body allows this pump to be used with a range of compatible chemicals as well as the new or used oils and engine coolants (RTU), diesel or oily water applications. Fully repairable and spare parts are readily available. Not suitable for flammable liquids.
