AdBlue Dispensers & Parts

DEF dispensers, urea-compatible meters, dedicated nozzles and the line parts that keep the whole circuit clean — one material spec from the tank to the vehicle filler neck.

Why the material list matters

AdBlue is not fuel

Three properties of a 32.5 % urea solution decide which parts can go on the line.

It attacks common metals

Copper, brass, zinc-plated steel and ordinary carbon steel are all corroded by urea solution. Wetted parts on this range are stainless steel or a specified polymer such as PPS.

It crystallises as it dries

Left to dry, the solution leaves crystals that jam nozzles and seize meters. Nozzles are self-draining and hose ends stay sealed between fills.

It freezes at −11 °C

Outdoor installations in cold climates need a heated cabinet or an insulated line. Tell us your site temperature range and we will size the heater and the tank connection.

Cabinets and Pump Sets

AdBlue Dispensers

Two Datian-built machines lead the range: a full-height forecourt unit and a slim column unit. Below them, a metered cabinet for a filling lane and two compact sets for a workshop, a farm tank or an IBC.

Forecourt & column dispensers

Datian forecourt AdBlue dispenser with fuel-dispenser display head
Forecourt unit · SALE / LITER / PRICE head

Forecourt AdBlue dispenser

A full-height machine in the same lane format as a fuel dispenser, so a site can sell AdBlue from its own bay instead of squeezing it onto the diesel lane.

  • Display head reads SALE / LITER / PRICE — the format a forecourt customer already knows
  • Full-height cabinet in white and orange with the ADBLUE marking
  • Single hanging nozzle with the hose stowed on the side of the body

Column unit · two-line LCD

Column AdBlue dispenser

A slim pedestal cabinet for sites that want metered DEF without a full lane — beside the shop door, in the truck park, at the wash bay.

  • Two-line LCD readout on the upper panel
  • Keypad behind a clear cover, with a key lock on the panel
  • Red AdBlue nozzle parked on a side hook, hose coiled at the base

Group A

Dispenser cabinet — metered

DT-ADB-1 AdBlue dispenser cabinet with diaphragm pump
Cabinet · ±0.3%

DT-ADB-1

A metered AdBlue cabinet driven by a diaphragm pump — the pump type that survives urea, because the liquid never reaches a dynamic seal or a set of metal gears.

  • Diaphragm pump with a urea-compatible meter on the discharge
  • ±0.3 % across the 40 L/min delivery range
  • 380 × 410 × 560 mm footprint; DC 12/24 V or AC 220 V supply
  • For urea (AdBlue), methanol and lightly corrosive liquids

Group B

Compact units & pump sets

DT-ADB-2 compact AdBlue dispensing unit
Compact · ±1%

DT-ADB-2

A shallow 500 × 280 × 400 mm unit that bolts to a wall or a post — for a service bay or a yard where there is no room for a floor-standing cabinet.

  • Diaphragm pump with a gear-type chemical meter
  • 40 L/min at ±1 %, on the same 550 W motor as the DT-ADB-1
  • DC 12/24 V or AC 220 V supply for vehicle or mains operation
  • For urea (AdBlue), methanol and lightly corrosive liquids

DT-ADB-3 methanol and AdBlue pump set
Pump set · 20 – 25 L/min

DT-ADB-3

No cabinet at all — a pump, a meter and a nozzle on a 320 × 350 × 220 mm base plate. Bolt it to a drum or an IBC and fill straight from the container.

  • Methanol / AdBlue pump set on a base plate, 320 × 350 × 220 mm
  • 20 – 25 L/min at ±1 % — the low-flow choice for cars and vans
  • AC 220 V or DC 12/24 V, so it runs off a vehicle battery on site
  • For urea, chemical liquids and water

AdBlue Line Parts

Everything between the tank and the filler neck. Each part on this list is stainless steel or PPS in the wetted path — no copper, brass or zinc anywhere the solution touches.

PPS oval gear pulse meter for urea service

PPS Oval Gear Pulse Meter

PPS body and PPS gears, so there is no metal in the metering path at all. Pulser output feeds a register or a controller. Two sizes cover the whole range.

ModelDT-ADB-M03 / DT-ADB-M05
Flow range20 – 100 L/min / 5 – 40 L/min
Size1" / 3/8", 1/2", 3/4"
MaterialPPS
ApplicationUrea, methanol, chemical

DT-ADB-M65 stainless steel four-piston urea flowmeter

Stainless Steel Urea Meter

Four-piston meter with a stainless steel cylinder liner inside an alloy body — the piston face that actually contacts urea is stainless, which is where a standard fuel meter fails first.

ModelDT-ADB-M65
Flow rate5 – 90 L/min
Discharge per revolution0.5 L
Accuracy±0.2%
Repeatability≤0.07%
ApplicationMetering urea solution

DT-ADB-J4 four-piston positive displacement DEF meter

DEF Positive Displacement Meter

Stainless steel in the wetted path, with a mechanical counter on the front face so it totals the delivery without any electronics on the line. Each revolution of the pistons passes 0.5 L, so the count is read straight off the drum.

ModelDT-ADB-J4
Discharge per revolution0.5 L
Flow range5 – 100 L/min
Working pressure0.12 – 0.35 MPa

DT-ADB-N05 AdBlue dispensing nozzle

AdBlue Nozzle

Dedicated urea nozzle with a 3/4" inlet and a 13/16" – 15/16" spout, so it will not physically fit a diesel filler neck — the cheapest way to stop a misfuel.

AdBlue dispensing

AdBlue fuel dispenser supply and after-sales

Why a urea dispenser is a different machine from a diesel pump, and what we hold.

An AdBlue fuel dispenser is not a diesel pump with a blue lid: the wetted parts, the seals and the meter are specified for urea, which is why we quote an AdBlue fuel dispenser as a complete unit rather than a conversion. As an AdBlue fuel dispenser manufacturer and an AdBlue fuel dispenser supplier we cover one to four nozzle layouts, and as a China AdBlue dispenser and a China AdBlue dispenser manufacturer we ship the whole island, including the AdBlue storage tank and the AdBlue dispensing system that connects it.

Export footprint by line: AdBlue dispenser China, handled by the same team that builds the diesel lanes. An AdBlue dispenser manufacturer and an AdBlue dispenser supplier are often two different companies; here they are one, so the AdBlue dispenser price already includes the diesel exhaust fluid dispenser nozzle, the hose and the breakaway. Ask for a DEF dispenser quotation and we will confirm which AdBlue dispenser China variant fits your island.

Crystals are the failure mode customers ask about most, so the parts list is built around them: a coalescing filter ahead of the meter, a stainless strainer at the nozzle inlet, and seals specified for urea rather than for diesel. If you are converting a diesel lane, send the pump model and the island layout first.
