Detailed description
Detailed description
The Whale Smartbail BP5012 manual bilge pump is designed for evacuating stagnant water, particularly for drying bilges. This model is installed through a bulkhead, providing a compact and discreet solution. Its design includes versatile 25 mm (1") and 38 mm (1 1/2") fittings, allowing adaptation to different plumbing configurations.
Performance and efficiency
The Whale Smartbail BP5012 delivers evacuation flow rates suited to requirements. With 25 mm fittings, it can reach a flow rate of 38.5 litres/min (10.2 US gals/min) at 45 strokes/min and up to 51.3 litres/min (13.6 US gals/min) at 60 strokes/min. For 38 mm fittings, flow rates are 43.5 litres/min (11.5 US gals/min) at 45 strokes/min and 58 litres/min (15.3 US gals/min) at 60 strokes/min. The pump supports a combined maximum suction lift and discharge head of 3 metres (9.8 feet).
Design and materials
Weighing 0.6 kg, the Smartbail pump is made from materials resistant to marine environments, including glass-fiber-reinforced polypropylene for the pump body, stainless steel, Nitrile for inlet and outlet valves, and Santoprene® for the diaphragm. Its self-sealing design, featuring a foam gasket, eliminates the need for additional sealants during installation. The BP5012 model complies with ISO15083. A maintenance kit (AK5010) is available for replacing rubber components if required.
Installation and use
The Smartbail pump is designed for single-person installation from one side of the bulkhead. It requires a circular cutout of 140 mm diameter (5½") and is secured with four 5 mm self-tapping screws after pilot holes of 3.5 mm are drilled. Inlet and outlet elbows can be oriented 360° for installation flexibility. The integrated handle allows instant activation and locking in the closed position after use. The pump can be operated by hand or foot, providing a reliable manual pumping solution.
