Its design has been tried tested and trusted by sailors for decades. This tough and lightweight polypropylene, manual bilge pump is a proven, reliable double-action pump that is supplied with 2 manifolds to empty 2 bilge compartments at the same time or empty one twice as quickly. The Mk5 will continue to pump even if one diaphragm fails. This heavy-duty bilge pump is ideal for larger craft where high output is vital.
