Draper 230V Surface Mounted Water Pump, 76L/min, 1100W

The Draper SP77 is a dependable, plug-and-play surface mounted water pump designed for the everyday water management needs of homeowners, gardeners, and property managers. Delivering up to 76 litres per minute from a 1,100W 230V motor through a 25mm outlet, it handles the full range of domestic and light commercial pumping tasks – draining water butts, feeding garden irrigation systems, supplying outdoor taps, transferring water between tanks, and clearing standing water from patios and drives.

Self-priming operation means setup is straightforward: connect the hoses, switch on, and the pump draws water automatically without manual priming. Thermal overload protection safeguards the motor against overheating, double-insulated corrosion and rustproof impellers ensure long service life, and a weatherproof on/off switch allows safe and convenient outdoor installation. Supplied with a 25mm output elbow and fitted with a 1.5-metre cable and approved plug, it's ready to connect to a standard mains socket and get to work immediately.

Key Features & Benefits

Self-Priming for Instant, Hassle-Free Operation

The SP77 primes itself automatically – no need to manually fill the suction line before starting. Connect the suction hose to your water source, switch on, and the pump draws water through and delivers it to the outlet. This makes it fast to deploy, easy to use without specialist knowledge, and practical for time-sensitive tasks like emptying a water butt before it overflows or responding to pooling water after heavy rain.

76L/min Output – Capable Everyday Flow

At 76 litres per minute (4,560 litres per hour), the SP77 delivers a solid flow rate for domestic and garden applications. Fill a 200-litre water butt in under three minutes, supply multiple sprinkler heads simultaneously, feed a drip irrigation network, or transfer water between storage tanks efficiently. For most home and garden pumping tasks, this output is more than adequate.

1,100W Motor – Powerful and Efficient

The 1,100W 230V motor provides the sustained power needed for continuous pumping duty without overloading. Running from a standard mains socket, the SP77 avoids the fuel costs, noise, maintenance demands, and exhaust emissions of a petrol pump – making it the natural choice wherever mains power is available and quiet, clean operation is preferred.

Thermal Overload Protection

If the motor overheats – from a blocked impeller, an unexpectedly demanding load, or extended high-temperature operation – thermal overload protection automatically cuts the power supply before damage can occur. Once the motor has cooled, it can be restarted normally. This protection is essential for a pump that may run unattended as part of an automated or semi-automated watering system.

Weatherproof On/Off Switch

The integrated weatherproof switch is rated for outdoor use, allowing the SP77 to be installed in exposed garden and outbuilding locations without requiring the switch to be separately housed or protected. Switch the pump on and off safely in all weather conditions.

Corrosion and Rustproof Double-Insulated Impellers

The pump's impeller assembly uses corrosion and rustproof materials with double insulation, engineered for long service life in outdoor water supply and garden irrigation applications where exposure to mineral-rich water, rain, and varying temperatures is routine. Built to perform reliably across seasons rather than needing early replacement.

Supplied with 25mm Output Elbow and Ready-to-Use Cable

The SP77 comes fitted with a 1.5-metre cable and approved mains plug, along with a 25mm diameter output elbow for immediate connection to standard pump hose. No additional adaptors or wiring required – plug into a mains socket, connect the hoses, and start pumping.

Lightweight and Easy to Position

At a compact size and modest weight, the SP77 is easy to carry, position, and reposition around the garden or property as needed. Surface mounting means it can be secured in a fixed location for permanent installation or moved between tasks as required.

Frequently Asked Questions

How does the SP77 differ from the Draper SP90MS multi stage pump? Both are self-priming 1,100W surface mounted pumps with thermal overload protection and weatherproof switches, making them broadly similar in design and application. The key difference is pressure capability. The SP90MS is a multi stage pump achieving a maximum head height of 46 metres (approximately 4.5 bar) – suited to mains pressure boosting, elevated tank supply, and high-pressure irrigation. The SP77 is a single-stage pump better suited to lower-head garden and home transfer applications. If your task requires pumping to significant height or maintaining high pressure across a long distribution run, the SP90MS is the right choice; for everyday garden pumping, irrigation supply, and water transfer at modest head, the SP77 delivers reliable performance at a more accessible price point.

What does self-priming mean in practice? A self-priming pump draws water up through the suction hose automatically when switched on, without needing the hose filled with water manually beforehand. For a domestic user, this simply means connecting the suction hose to the water source, switching the pump on, and letting it work. It's considerably more convenient than a non-self-priming pump, especially for occasional or irregular use.

Can I leave the SP77 installed outdoors permanently? The weatherproof switch allows outdoor operation in all conditions, and the rustproof impeller construction supports outdoor installation. For extended outdoor use, protecting the motor body from direct rainfall – with a simple pump cover or outbuilding installation – will extend service life. Always follow the manufacturer's installation guidance and ensure the mains connection is made via an outdoor-rated RCD-protected circuit.

Is the SP77 suitable as a submersible pump? No. The SP77 is a surface mounted pump and must not be submerged. It draws water via a suction hose from a separate water source. For submersible applications, a dedicated submersible pump is required.

What water types can it handle? The SP77 is designed for clean and lightly filtered water – garden water butts, storage tanks, mains supply boosting, and similar sources. It is not suitable for pumping dirty water, silt, or water carrying particles larger than fine sediment. For dirty water applications, refer to the Draper Expert petrol pump range.

Does it come ready to plug in? Yes. The SP77 is supplied with a 1.5-metre cable and approved mains plug already fitted, along with a 25mm output elbow. Connect to a standard 230V mains socket, attach your hoses, and it's ready to operate.
