UM4S
Standard FillTruck-supplied
The standard for filling DEF urea storage tanks. The brushed stainless-steel enclosure looks great on building walls for the long term, and accepts hose connections from pump-equipped DEF delivery trucks. Designed for 1–4 tanks with 85-90-95% high-level monitoring and overfill prevention.

Built for safe DEF fills
Fill DEF tanks without the risk.
Delivery-truck hose connections
Accepts hose connections from pump-equipped DEF delivery trucks through a 2″ adapter with ball and check valves.
At grade or on the rooftop
The UM4S fills at-grade tanks on the truck's pump; the UM4P adds an onboard pump to reach upper levels and rooftops.
Automatic overfill prevention
Tank levels — particularly 85-90-95% high levels — are monitored, and actuated valves close the fill pipe on high level.
Spill containment built in
A 3-gallon containment basin — with optional hand pump — catches drips from hose disconnects at the fill point.
Equipment & options
Configured for your install.
Both stations ship with a complete adapter, valve, sensor, and containment package, and adapt to the tank count, mounting, and control requirements of the site.
