Detailed description

The Maintenance kit for Whale AK8050 Mk5 Universal pump is a complete maintenance solution designed to restore the performance of Whale Mk5 Universal and Henderson Mk5 Universal manual bilge pumps. This kit provides all the wear parts needed for a full overhaul, ensuring the continued reliability of your bilge system. It is intended to extend the lifespan of pumps used for manual pumping of bilge water, salt water, or diesel.

AK8050 service kit contents

The AK8050 kit contains a complete set of spare parts for overhauling your pump, with specifications suitable for single- or double-action models. For a single-action pump, the typically included items are:

1 inlet valve plate
1 inlet valve
2 long valve screws (or 2 short valve screws)
1 upper cover gasket
1 diaphragm (often made of neoprene)
1 outlet valve
2 long valve screws
2 large circlips
2 small circlips
8 M5 x M25 screws
8 M5 nuts

For double-action pumps, the kit may include double the quantity of most of these components, such as two inlet valve plates, two inlet valves, two upper cover gaskets, two diaphragms, two outlet valves, four short valve screws, four long valve screws, four small circlips, and two large circlips.

Context: the Mk5 Universal pump

The Whale Mk5 Universal manual bilge pump, for which this kit is designed, is characterized by high pumping capacity, reaching up to 66 litres per minute for single-action models and up to 104 litres per minute for double-action models. It is constructed from lightweight, durable materials, including glass-reinforced polypropylene, acetal, nitrile, and stainless steel for fluid-contact components. This pump offers three versatile mounting options: on deck, through deck, or on bulkhead, and can handle a maximum suction and discharge head of 4.5 metres. It is approved by Lloyds (MCA) and USCG, making it compliant with ISO15083 as a primary bilge pump for vessels 12 metres or longer.

Ease of maintenance for the Mk5 Universal pump

The Mk5 Universal pump’s design incorporates features aimed at simplifying maintenance, such as an inspection hatch that requires no tools for access. It is equipped with anti-clogging valves and a fully protected diaphragm, contributing to its reliability. An ergonomic handle and odour-resistant seals further enhance its user-oriented features.

Expert opinion

« AK8050 maintenance kit: the key to the longevity of your Whale Mk5 pump »

Whale’s AK8050 service kit is a strategic solution for owners of sailboats equipped with a Mk5 Universal or Henderson Mk5 Universal manual bilge pump. Instead of replacing the entire pump—known for its robustness and compliance with standards (Lloyds, USCG, ISO15083)—this kit targets the replacement of wear parts. It is essential for maintaining the efficiency of the bilge system, a critical safety element aboard, especially on vessels 12 meters or longer where this pump may serve as the primary bilge pump.

Installing this kit is within the capability of a sailor with basic mechanical skills. It involves disassembling the existing pump to replace the valves, diaphragm, and seals. While this operation requires minimal tools and methodical work, it is simplified by the Mk5 Universal pump’s design, which includes a tool-free inspection hatch. Using this kit ensures not only the original hydraulic performance (high flow rate, discharge capacity) but also the continued validity of the pump’s safety certifications.

The main advantage of the AK8050 lies in its cost-effectiveness. It extends the service life of a reliable piece of equipment at a marginal cost compared to purchasing a new pump. It is a relevant investment for any preventive or corrective maintenance, ensuring the pump remains operational and performs under all conditions, whether handling bilge water, seawater, or even diesel.
