SP20ESM Water Pump

The SP20ESM is a dewatering pump built around the same half-horsepower motor as the SP20E, but with an impeller and casing made from a blended rubber compound instead of cast iron, rated to handle up to 68 gallons per minute of flow, or about 4760 gallons in a full hour of steady pumping.

Rubber compound instead of cast iron

Swapping cast iron for a blended rubber compound on the impeller and casing trades some raw toughness for better resistance to abrasive wear from sand and grit, which can mean a longer working life in muddy or silty water specifically. At 24 pounds, it is also noticeably lighter to haul around a job site than a cast-iron equivalent of similar output.

Flexible discharge, same protection

Unlike a pump limited to one discharge direction, the SP20ESM's 2-inch port adjusts for either side or top discharge, letting you run the hose vertically or horizontally depending on your setup. The same double mechanical seals, housed in a liquid-paraffin-filled chamber, guard against dry-running damage, and a built-in thermal protector shuts the motor down before overheating becomes a problem. A 20-foot uni-body cord keeps the connection watertight.

Can the discharge port be switched from side to top? Yes - this model is built to discharge either vertically or horizontally.

Is it repairable rather than disposable? Yes, it is designed to be completely rebuildable, with every part replaceable.
