AIR OPERATED DIAPHRAGM PUMP - 1/2" DDP13 Macnaught

The DDP13 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. Multi-ported inlet and outlet manifolds offer a variety of options when making fluid connections. The all Polypropylene 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.
