Same as for the steel hand pumps but with the following additions:
- Durable glass-filled nylon reservoir and nylon encapsulated aluminum pump base for maximum corrosion resistance and lightweight handling.
- Two-speed pump operation on models 920511 and 925014 reduces handle strokes by as much as 78% over single speed pumps.
- Integral 4-way valve on the model 925014 for operation of double-acting cylinders.
- Handle lock for easy carrying.
- Non-conductive fiberglass handle for operator safety.
