A dispenser is only as fast as the hydraulic set inside it. The T-series unit on our assembly line right now carries our own CP8 high-flow pump, our own J6 flow meter, and the solenoid valve and pulser that link them. On test it delivered 110 L/min drawing from an underground tank and 125 L/min from an above-ground tank.
What is on the assembly line
The cabinet in these photographs is a T-series fuel dispenser, the compact model that carries its own pump and meter inside the frame. Everything between the tank and the nozzle is bolted into this one frame, which is what lets a T-series unit work tank-side, inside a bund wall, or alongside a containerised tank.
The four components
All four are made in our own plant rather than bought in and re-badged.
- CP8 combined vane pump — the high-flow unit in our vane combined pump range. Rated flow is 140 L/min from a 1.1 kW motor at 660 rpm, with an output pressure of 0.18–0.35 MPa and a dry vacuum of at least 0.054 MPa. It runs gasoline, diesel, kerosene and mixed fuels, on roller bearings, with a generously sized oil and gas separation chamber.
- J6 (DTJ6) flow meter — our high-capacity dispenser meter. Flow range 5–160 L/min, accuracy ±0.2% between 5 and 100 L/min, repeat error at or below 0.1%, working pressure 0.12–0.35 MPa, and a rated working life of 10,000,000 litres. It discharges 1 litre per revolution and is a direct fit for DT-G, DT-L, DT-T and Classic dispensers.
- Solenoid valve — the on/off valve on the discharge line, made in our own workshop. Inlet and outlet can be reversed to suit the piping direction, and the port is available threaded or plain.
- Pulser — the rotary pulse sensor that turns meter rotation into the signal the controller counts. Ours are built and sealed in the same plant as the meters they sit on.
The flow test
Every dispenser is flow-tested before the panels go on. The set in these photographs was run on two supply arrangements:
| Supply arrangement | Measured flow rate |
|---|---|
| Fuel drawn from an underground tank | 110 L/min |
| Fuel drawn from an above-ground tank | 125 L/min |
Both numbers come off the same pump, meter, valve and pulser. The only thing that changed between the two runs was where the fuel was drawn from.
Why we cast the bodies ourselves
The brass valve body above carries our own mould number and the DATIAN name cast into the metal, not printed on a label. Pump bodies, meter housings and valve bodies are cast to our drawings and machined in our own plant, so the pump, the meter and the valve on this frame were dimensioned to fit each other before they ever met.
That shows up years later, when something needs replacing. A dispenser built from a mix of bought-in hydraulics is only as serviceable as its least available part. When the pump, the meter, the valve and the pulser all come from one factory, so does the spare.
The same hydraulic set goes into other dispensers in the range, and the DTJ6 flow meter is also supplied on its own as a replacement part. If you are specifying a high-flow dispenser for a depot or a containerised station, tell us your tank arrangement and the flow rate you need and we will match the pump and meter to it.
