Dayton 4HA32 trap piston PVC 11/16 in OD

Product Identity

The Dayton 4HA32 is a hand-operated drum pump with a PVC piston and an 11/16 in outside diameter. It is built for transferring ammonium, detergents, most acids, oils, rinse additives and soda ash from buckets, drums or pails. The self-priming design includes a bung adapter made of polypropylene and a spout, while Viton seals resist chemical attack. This unit suits maintenance crews and plant operators who need portable, manual fluid transfer without metering.

Upgrade Path

The pump replaces manual pouring or siphoning methods that risk spills and vapour exposure when moving corrosive or viscous liquids from open containers. The jump is worth it when the operator must handle chemicals listed in the compatibility chart and requires a sealed bung connection to meet site safety rules. It is not for buyers who need metered dispensing, an included discharge hose or a nozzle for directed flow into narrow openings.

Sustained Operation

Under continuous hand stroking the PVC piston and Viton seals maintain prime and resist degradation from the approved chemical range. The simple mechanical action avoids motor heat or electrical hazards, so output stays consistent as long as the operator can maintain the stroke rhythm. It is not for users who require automated, high-volume transfer over extended shifts without operator fatigue.
