Review WHALE Gulper Grouper Pump Fishbox Discharge One Size Mk

The Whale GP4572 Gulper Grouper Pump is a versatile and efficient marine pump designed specifically for the discharge of fish or other cargo from a fishbox or hold. This pump is part of Whale's renowned range of marine pumps, known for their robustness, reliability, and high performance.

The GP4572 is a diaphragm pump, which means it operates by creating a vacuum on one side of a flexible diaphragm and pressing the liquid to the outlet on the other side. This design ensures a positive displacement of the liquid, providing consistent flow rates and minimizing the risk of air ingress. The pump is powered by a reliable, powerful 12V DC electric motor, which is both efficient and quiet in operation.

The pump's gulper design allows it to handle large volumes of liquid with ease. The impeller has a large opening, which enables it to draw in a significant amount of liquid with each cycle. This feature makes the GP4572 an excellent choice for applications where fast discharge is required, such as on fishing vessels or aquaculture operations.

The GP4572 is also designed with the marine environment in mind. It is built with corrosion-resistant materials, including the diaphragm, impeller, and motor casing. The pump is also sealed to prevent water ingress, ensuring that it can operate reliably in even the most challenging marine conditions.

The pump's discharge is configured with a 3/4" BSPT outlet, which is compatible with a range of hose and pipe connections. The outlet is also equipped with a check valve, which helps to prevent backflow and maintain the integrity of the discharge system.

The GP4572 is a compact and lightweight pump, weighing only 12.8 kg (28 lbs), making it easy to install and transport. It is also easy to maintain, with accessible components and a simple design that allows for quick and straightforward servicing.

In summary, the Whale GP4572 Gulper Grouper Pump is a high-performance, reliable, and corrosion-resistant marine pump designed for the efficient and effective discharge of fish or other cargo from a fishbox or hold. Its large gulper impeller, powerful motor, and robust design make it an excellent choice for a wide range of marine applications.
