Steel Hand Drum Pump

The Dayton 4AYD4 is a lever-operated pump built entirely from steel with a powder-coated housing and PTFE and Viton seals. Its self-priming piston design draws petroleum-based media, biodiesel and E85 fuels directly from a drum without metering. The 3/4 inch OD outlet and extra-long body allow refill containers to sit on the drum during filling.

For bio-diesel and E85 transfer only

This pump suits workshops and farms moving high-alcohol or bio-diesel blends where fracture-proof steel construction and compatible seals are required. It is not suited for metered dispensing, automatic operation or fluids that attack PTFE or Viton. Buyers needing an included discharge hose or electric drive should look elsewhere.

3/4 inch OD steel outlet

The outlet’s 3/4 inch outside diameter and all-steel pump head determine whether the pump connects to existing drum bungs and hose fittings without adapters. Verify that dimension against your drum hardware before purchase.

Questions about this item

How does the self-priming design work once the pump is inserted into a drum?

The lever action creates suction on the upstroke so liquid rises without manual priming, then discharges on the downstroke for continuous flow.

What fuel types are the PTFE and Viton seals rated to handle?

The seals are compatible with petroleum-based media, biodiesel blends and E85 fuel without degrading.

What size bung opening does the steel pump head fit?

The 3/4 in OD pump body is designed to thread into a standard drum bung for a secure, fracture-proof mount.
