Datian makes the parts that live inside a fuel dispenser: combination pumps, flow meters, solenoid valves and pulse sensors. We also have an unusual claim on Bennett — from 2001 we were the Chinese partner in Bennett's Shanghai joint venture, and dispenser components have been our business ever since. So this page is about buying Bennett replacement parts from a company that once built parts for Bennett itself.
What Datian and Bennett actually did together
The record here is public, so it can be checked rather than taken on trust. Bennett Pump Company was founded in Michigan in 1919. Hines Corporation acquired Bennett Pump in 1998. Then comes the part that matters to a buyer in Asia:
- 1999–2001 — Bennett sets up its China joint venture. Hines Corporation's own corporate history records it as "Bennett Pump establishes a China-based joint venture, Shanghai Bennett". Bennett's president at the time, Tom Thompson, described the deal to Crain's Grand Rapids Business as a signed agreement with a Chinese firm, Zhejiang Datian Machine Co., to produce fuel meters and pump units and eventually complete dispensers for the Asian market, under the name Bennett Shanghai Machine Co., with a manufacturing plant in Shanghai.
- 10 May 2001 — the joint venture is registered. Shanghai Bennett Machine Co., Ltd. is entered on the Shanghai register on 10 May 2001 with registered capital of USD 300,000 and Spencer Lee Hines as legal representative. Its registered business scope covers the design, production and processing of pumps, positive-displacement liquid meters, valves and dispensers, and the parts for them — which is precisely the component set Datian already made.
- 2007–2008 — the joint venture becomes wholly owned. Hines Corporation's history records that it acquired the joint venture partner's share of Shanghai Bennett. From that point Shanghai Bennett is a wholly owned Bennett subsidiary, not a joint venture, and Datian holds no equity in it.
- Since then — component supply. Datian has continued as an OEM component supplier to the dispenser industry, naming Gilbarco, Bennett, Tokheim and Censtar among the brands it supplies.
Two things follow from that, and both are stated plainly because a buyer deserves to know which is which. Datian is not Bennett, is not a Bennett subsidiary and is not authorised or endorsed by Bennett. What Datian is, is a company that spent the joint-venture years manufacturing pumps, meters and valves in the same programme, and has kept making them since.
The four families a Bennett forecourt actually consumes
A dispenser is a cabinet around a hydraulic set and an electrical set. Both wear, and the hydraulic side — the part of the trade that gets called Bennett hydraulics — wears first, because it is the side the fuel passes through. These are the four families we build, and the numbers below are the ones published on our product pages, not a summary of them. They are also the four families a Bennett dispenser replacement turns on, because a failed hydraulic set is usually what decides whether the cabinet is repaired or retired.
1. Combination pumps and submersible pumps
The JBL50 is a vane combination pump for gasoline, kerosene, diesel and mixed gas-and-liquid media: rated flow 60 L/min, driven by a 0.75 kW motor at 660 rpm, output pressure 0.18–0.35 MPa, dry vacuum at least 0.054 MPa, noise at or below 72 dB, in an aluminium alloy shell with a clean cast finish. Suction and air separation sit in one unit, so entrained air is separated from the fuel before delivery. It is the natural counterpart to a combination pump replacement on a Bennett-style cabinet.
Where the site lifts from the tank instead of from a suction line, the DT-STP submersible turbine pump range covers six models from 0.75 HP to 5 HP, 210 to 1000 L/min at a maximum head of 29–30 m and 230–300 kPa, under type examination certificate IEP 26 ATEX 1836X for Zone 0 and Zone 1. For a Bennett submersible pump replacement the discharge head has to land on the tank flange already in the ground and the column pipe length follows the burial depth — see the DT-STP range for the full table.
2. Flow meters
The DTJ100 is our dispenser flow meter: flow range 5–100 L/min, accuracy ±0.2% across that whole range, repeat error at or below 0.1%, working pressure 0.12–0.35 MPa, 0.5 litres discharged per revolution, and a rated working life of 10,000,000 litres. It is built to be a direct dispenser component or a replacement meter, and it is what usually goes in when a Bennett flow meter replacement is being quoted. Metering is the one part where a wrong part is not a nuisance but a compliance problem, so the flow meter range lists every range and pressure separately.
3. Solenoid valves
The D20-F is a flameproof dual-flow control valve in a brass-forged body: the coil sits inside a flameproof enclosure driven by a built-in stacked electromagnetic pilot valve, and two-stage flow keeps metering accuracy high across the whole delivery range. Nominal diameter 20 mm (3/4 in), flow rate 3–50 L/min with the small-flow stage set at 3–3.5 L/min, working pressure 0.035–0.35 MPa, and a main diaphragm rated down to −40 °C. Coils cover AC220 V, AC230 V, AC115 V, AC110 V, DC12 V and DC24 V. The series carries certificate CNEx 15.4019 / Nemko 05ATEX1275X, and it is offered in flameproof and encapsulated builds at DN20, DN25 and DN40 — the three sizes that cover most Bennett solenoid valve replacement work. Full data is on the D20-F page, and the DN25 and DN40 builds sit alongside it on the valve and sensor range page.
4. Pulse sensors (pulsers)
The DT-Q3 is a compact explosion-proof pulser in an aluminium housing, 123 × 80 × 60 mm, running on 5–12 VDC at 30 mA and putting out a dual-channel square wave at 100 or 200 pulses per revolution, up to 300 r/min, rated Ex d II B T4 Gb under certificate CNE×15.3571. A built-in anti-reverse mechanical counter keeps a local total independent of the electronics. On a Bennett pulser or a Bennett sensor the pulse count has to match the metering board, or the volume reading will be wrong even though the dispenser runs perfectly — the three models are listed under pulsers and sensors.
Naming the part, the way buyers ask for it
Half the friction in a replacement order is naming. These are the same four families written the way purchasing departments and service crews actually send them, so quote whichever line matches what you are holding:
- Bennett pump parts — JBL50 and the wider combination pump range
- Bennett pump replacement — whole pump, or pump plus motor as one unit
- Bennett combination pump — vane type, 60 L/min class
- Bennett submersible pump — DT-STP, 0.75–5 HP, ATEX
- Bennett STP replacement — head, column pipe and motor sized to the site
- Bennett flow meter — DTJ100, 5–100 L/min
- Bennett flow meter replacement — meter only, no cabinet work
- Bennett solenoid valve — DN20 / DN25 / DN40, flameproof or encapsulated
- Bennett solenoid valve replacement — quote voltage and flow setting
- Bennett pulser — 100 or 200 pulses per revolution
- Bennett sensor — pulser or junction box, Ex rated
- Bennett dispenser parts — the cabinet side, not the hydraulic side
- Bennett fuel dispenser parts — same list, the phrase fleet buyers use
- Bennett spare parts — the phrase used on maintenance contracts
- Bennett replacement parts China — sourcing direct from the factory
- Bennett pump parts China — same order, priced ex-works
If the phrase you use is not on that list, send it anyway. What matters is the part, not the wording. Datian has been a Bennett pump parts supplier since those joint-venture years, and any Bennett parts supplier can quote a part number — fewer of them can tell you what actually changed between what you are holding and what will arrive.
"Bennett compatible" is a fit statement, not an origin statement
The industry uses "Bennett compatible" loosely, and it is worth being exact about it. A part is Bennett compatible when its mounting pattern, port threads, flange layout, pulse count and electrical characteristics match what the dispenser expects. That is a statement about geometry, and it is the statement Datian makes. It is not a claim about who manufactured the original, and it is not a claim to be a genuine Bennett part. Nothing here replaces Bennett's own service network either, and no part on this page is a replacement for Bennett parts in the sense of having been made by Bennett.
So the honest position is this: we know these families because we built them inside a programme Bennett set up in Shanghai, we publish the numbers rather than describing them, and if a part does not match we say so before the order is placed instead of after. If you are working out whether to replace Bennett parts one at a time or to replace the dispenser, start from the numbers on the about page, then send us the model and we will answer with the part.
Bennett and Bennett Pump are trademarks of Bennett Pump Company. Datian Machine is not affiliated with, authorised by or endorsed by Bennett Pump Company; the names appear here only to describe the equipment our parts are bought to replace.
Send the part, not the story
For any of the four families, the fastest quotation comes from four things: the model you are taking out, the thread or flange pattern, the voltage for anything electrical, and the flow or pulse count you need. Add a photograph of the nameplate and we can answer within 24 hours. Datian supplies Bennett replacement parts, Bennett dispenser parts and the wider set of Bennett spare parts to distributors and service companies worldwide — request a quotation and we will tell you which of the four families your part is in.
