Review WHALE Water Systems Pump Compact 50 Thru deck

The Whale 71957 Water Pump is a high-performance, reliable solution for your onboard water system needs. This pump, part of Whale's 50 Thru-Deck range, is designed to deliver large volumes of water with minimal effort, making it an excellent choice for boats with high water demand or for those who desire a quick and efficient water supply.

The 71957 Water Pump is a diaphragm pump, which means it employs a flexible diaphragm instead of a traditional impeller to move water. This design feature offers several advantages: it's self-priming, meaning it can start pumping water as soon as it's submerged, even if the water level drops; it's quieter than conventional pumps due to the absence of an impeller; and it's also more resistant to damage from debris or foreign objects in the water.

This pump features a powerful 12-volt DC motor with a maximum flow rate of 18 liters per minute and a maximum head pressure of 10.5 meters. It's capable of delivering water to multiple outlets simultaneously, such as a shower, sink, and washdown system, without any noticeable drop in pressure.

The 71957 Water Pump is designed for easy installation, with a compact, low-profile housing that fits neatly through a standard 76mm (3 inches) thru-hull. It comes with a 2.3-meter (7.5-foot) cable and a 0.8-meter (2.6-foot) suction hose, ensuring ample length for most installations. The pump's housing is constructed from marine-grade materials, ensuring durability and resistance to corrosion, while the diaphragm is reinforced with stainless steel for added strength and longevity.

The Whale 71957 Water Pump is not only powerful and efficient but also easy to maintain. Its open design allows for easy access to the diaphragm for inspection and replacement, while the pump's self-draining feature eliminates the need for constant priming. Additionally, the pump comes with a built-in check valve to prevent backflow, ensuring that water stays where it's supposed to in the system and not in the bilge.

In summary, the Whale 71957 Water Pump is a versatile, powerful, and efficient solution for your onboard water system needs. Its self-priming diaphragm design, quiet operation, and easy installation make it an excellent choice for boaters who require a quick and reliable water supply. With its robust construction, durable materials, and easy maintenance, the 71957 Water Pump is a must-have for any boater's toolkit.
