EPDM seals for chemical resistance

The WMP20 features EPDM seals, a type of rubber material that is designed to be compatible with a wide range of chemicals.

Easy starting Honda OHV commercial engine

The durable Honda GX series commercial grade engine is easy starting and provides ample power for the toughest conditions.

220 gal./min capacity

Thermoplastic components for chemical capability

The WMP20's reinforced thermoplastic housing, volute & impeller improve chemical resistance.

Heavy duty full frame protection

Protects the pump, while offering a convenient tie down location for transport.

Isolation mounted engine and pump

High performance mounts minimize vibration, keeping the pump from “walking” away or “burying” itself in soft soil conditions. The reduced vibration also reduces wear on components, increasing the pump's durability.

Protected by Honda Oil Alert®

Protects the pump by shutting the engine off when low oil is detected.
