How to choose the right fuel purifier
Start with the system duty, then compare the five models against actual flow and installation requirements.

5×16
Need a compact installation?
Start by comparing the 5×16 with your available space, line connections and actual pump flow. Confirm its suitability against the current model data sheet.

5×24
Comparing a mid-length chamber?
Include the 5×24 when reviewing a stationary or circulation duty. Match the operating flow and installation dimensions together.

5×32
Considering a longer chamber?
Compare the 5×32 with the 5×24 using the confirmed flow and available height. Chamber length alone does not determine the correct model.

8×30
Planning a larger installation?
Include the 8×30 when assessing larger equipment, fuel transfer or fuel-dock duties. Check the flow, connection sizes and support requirements.

8×51
Evaluating a larger fuel-handling duty?
Compare the 8×51 with the 8×30 using normal and peak flow, mounting space and draining access. Obtain confirmation for your operating conditions.
When should you assess purification or polishing?
For free-water and heavy-contamination separation in a fuel line, assess the purifier at the proposed installation point. For cleanup of bulk stored fuel, assess a complete polishing loop including pumping, separation and appropriate filtration.
A clear selection workflow
- Define the application, fuel type and contamination condition.
- Record normal and peak flow through the purifier.
- Check pressure, connections, space and mounting.
- Compare current model data sheets with system requirements.
- Confirm suitability, draining and follow-up verification.
Do not size by engine horsepower or tank volume alone. Purification does not replace required fine filtration or address every aspect of fuel quality.
Need help choosing a model?
Prepare the equipment and pump models, flow, line pressure, connection sizes, available space and a system photo or sketch. For a tank-circulation duty, add the tank volume and cleanup objective.

Frequently Asked Questions (FAQ)
What is a filterless fuel purifier, and how is it different from a fuel filter or water separator?
A Dieselcraft filterless fuel purifier separates free water and heavy contamination from diesel fuel using a long residence-time chamber and proprietary separation media — not a replaceable filter cartridge. Unlike a conventional spin-on fuel filter or coalescing water separator, there is no filter element to buy, stock, or change; contamination and water settle out and are removed through a bottom drain valve. This eliminates recurring filter-replacement cost and the risk of a clogged filter starving the engine of fuel. ANKORZ, as Dieselcraft’s Strategic Fuel Solutions Partner across Saudi Arabia, the UAE, Qatar, Oman, and Bahrain and the wider Middle East, supplies the full Dieselcraft filterless purifier range for stationary diesel systems.
Which Dieselcraft purifier model fits my pump flow rate and engine size?
Model selection is based on maximum flow rate (GPM) and the stated engine horsepower range: the 5×16 (15 GPM, 400–1,200 HP) suits compact stationary pumps and generators; the 5×24 (20 GPM, 600–1,500 HP) suits circulation pumps rated 4–7 GPM; the 5×32 (18 GPM, 600–1,500 HP) suits higher-flow pumps rated 8–18 GPM needing maximum residence time; the 8×30 (25 GPM / 1,500 GPH, 1,200–2,000 HP) suits stationary pumps, gen sets, locomotives and fuel docks; and the 8×51 (40 GPM / 2,400 GPH, 1,200–2,000 HP) is the highest-flow unit for high-volume fuel docks and continuous-duty stationary systems. ANKORZ can match flow rate and engine range to the correct model for a Gulf-region installation.
How much maintenance does a Dieselcraft purifier need if there is no filter element?
Maintenance is limited to periodically draining accumulated water and sediment from the bottom drain valve — there is no filter cartridge to replace, clean, or dispose of. All Dieselcraft purifiers in the range carry a five-year warranty and are rated to remove 99% of water and 95–98% of heavy particles from diesel fuel, so drain frequency depends on fuel quality and contamination load rather than a fixed filter-change interval.
Can Dieselcraft fuel purifiers be used with gasoline?
No. Dieselcraft purifiers are designed and rated for diesel fuel; the 8×30 and 8×51 models are explicitly stated as not for use with gasoline, and the same diesel-only design applies across the 5-inch series (5×16, 5×24, 5×32).
How should a Dieselcraft purifier be installed — orientation, inlet/outlet size, and clearance?
All models install vertically with a bottom drain valve, using forged-steel NPT inlet/outlet connections (1/2 in. on the 5×16, 1 in. on the 5×24 and 5×32, 2 in. on the 8×30 and 8×51). Overall height ranges from about 17.8 in. (5×16) to 35.86 in. (5×32) in the 5-inch series, and about 31.93 in. for the 8×30 tank; the 8×51 adds adjustable legs bringing port height to 42.6–46.6 in. Sufficient vertical clearance and access to the bottom drain valve should be planned for at installation.
What is the difference between fuel purification and fuel polishing?
Fuel purification (this product line) is inline, continuous, filterless separation of free water and heavy contamination from fuel as it flows toward the engine, with no moving parts beyond the drain valve. Fuel polishing is a separate, typically portable or skid-mounted process that circulates fuel out of a storage tank, through filtration and/or water removal, and back into the tank to clean up bulk stored fuel — see ANKORZ’s Fuel Polishing Solutions for tank-cleaning systems.
Why do stationary diesel systems in the Gulf need fuel purification even with clean delivered fuel?
Standby generators, belly tanks, and bulk diesel storage across Saudi Arabia, the UAE, Qatar, Oman, and Bahrain often sit idle between uses while ambient temperatures swing significantly day to night, causing condensation inside the tank. This water ingress promotes microbial growth and sediment buildup over time even when fuel was clean at delivery. A Dieselcraft purifier installed ahead of engine filtration continuously removes this water and heavy contamination before it can damage injectors, fuel pumps, or filters.
What percentage of water and contamination does a Dieselcraft purifier remove?
Every model in the Dieselcraft filterless purifier range — 5×16, 5×24, 5×32, 8×30, and 8×51 — is rated to remove 99% of free water and 95–98% of heavy particles from diesel fuel before it reaches the engine’s own filtration system.
Does a Dieselcraft purifier need electrical power to operate?
No. Separation relies on gravity and residence time as fuel flows through the chamber — there are no moving parts, filter media, or electrical components in the purifier itself. Water and sediment collect at the bottom and are removed through the manual drain valve.
Fuel care works best as a sequence
Purification protects fuel on its way to your equipment. Pair it with a test to prove the result, and with polishing for fuel that is already stored.
