Every Sequence pump is made in the USA from domestically sourced components of the highest quality and rigorously tested for integrity, flow and pressure.

Ultra-efficient Baldor motor is totally enclosed/fan-cooled for maximum durability and longevity.

Sequence pumps generate minimal noise.

Comes with a 3-Year limited warranty.

The Sequence Model 4000 series provides tremendous flow rates above and beyond other competing pumps in its category.

This pump is an end-suction centrifugal unit designed for installation outside of the water, keeping you dry and your fish safe.

It features exceptionally rugged construction, including a rebuildable, industrial-grade engine that is totally-enclosed/fan-cooled, with an aluminum-alloy housing; stainless steel hardware; and dry-run-resistant mechanical seals. The housing for the unit itself is injection-molded out of high-strength, glass-filled Noryl polypropylene, which is engineered for maximum resistance to corrosion, heat, cold and UV rays. Every Sequence pump is marinized, and can be easily converted for use with swimming pools or salt water.
