Danfoss OMR 400 dealer, supplier or distributor: how to choose Searching for a Danfoss OMR 400 turns up quotes that look alike and aren’t. Some sources sell a motor from another series with “400” in its name, and the OMR 400 itself is no longer in production. Pick the wrong source and you can end up with a motor that doesn’t fit your machine. This guide shows what each kind of seller does, which motors get confused and how to check a quote. Advance Hydraulic Works works with hydraulic pump and motor repair and supply from Delhi NCR, and this is how we’d go through it with you. Is the Danfoss OMR 400 still made? A Czech reseller lists the OMR 400, at 400 cm³, as no longer in production and replaced by the OMR X 400, product ID 11185535. It describes the maker as White Drive Motors & Steering, formerly Danfoss and Sauer-Danfoss. So a source selling a “new Danfoss OMR 400” is holding old stock, selling the OMR X replacement, or selling something else. Ask which. Danfoss OMR 400 dealer: what a dealer does A Danfoss OMR 400 dealer usually sells to end users from limited stock or on order. That suits a one-off replacement. Ask any dealer, Advance Hydraulic Works included, for the part number, maker and warranty in writing before you pay. Danfoss OMR 400 supplier: what the word covers Supplier is the broadest term. A Danfoss OMR four hundred dealer can sell new, antique inventory or aftermarket elements, and the word says nothing approximately authorisation. Ask exactly what is being supplied and who made it. Danfoss OMR 400 distributor: what a distributor does A Danfoss OMR four hundred distributor typically buys in quantity from the maker or an accepted chain, holds stock and frequently supplies dealers. That helps with repeat or fleet orders. Authorised status is a claim you can check, so ask for the agreement or confirm with the maker. What do 400 cm³ motors cost? These are overseas listings. None is an Advance Hydraulic Works price, and none is an OMR 400: • OMT 400, part number 151B3004, at €1,399.48 excluding VAT, in stock. • OMS 400, part number 257151F0605, at €1,200.49 including VAT. • OMV 400, part number 151B3106, aftermarket, at US$854.60. • OMT 400, part number 151B3010, aftermarket, at US$697.60. • OMR X 400, 11185535: price on request. Series, maker, shaft and warranty explain the spread. Be wary of a price far below these for a “new Danfoss” motor. The method: part number, maker, spec, proof 1. Part number. Get the full code, including the series letters. 2. Maker. Ask whether it’s Danfoss old stock, White Drive or aftermarket. 3. Spec. Confirm displacement, shaft, flange and ports. 4. Proof. Ask for the datasheet, a nameplate photo, lead time and a written warranty. A worked example Your machine runs on 60 L/min. Theory for a 400 cm³ motor is 60 × 1000 ÷ 400 = 150 rpm. You get three quotes. Source A offers an “OMR 400, in stock” with no part number, and it’s the cheapest. Source B offers an OMR X 400, 11185535, names the maker, and sends the datasheet and warranty in writing. Source C offers a “400 motor” that turns out to be 315 cm³ with a matching flange. Source C’s motor would spin at about 190 rpm, since 60,000 ÷ 315 is about 190. That’s 27% faster than you need, with about 21% less torque at the same pressure. Source A may be fine, but it can’t tell you what it is. Ask for the nameplate photo before you pay. This is illustrative arithmetic, so use the current datasheet for your actual motor. Implementation steps 1. Photograph the vintage motor’s nameplate, shaft and flange, and word the series letters. 2. Write down the part quantity and the displacement. 3. Work out your expected velocity from drift × one thousand ÷ displacement. 4. Decide whether or not you want the identical collection or the OMR X substitute. 5. Send the whole thing to Advance Hydraulic Works and ask what’s to be had. 6. Ask every supply to state maker, element range, situation, assurance and lead time in writing. 7. On arrival, compare the plate, shaft and ports with the vintage motor before fitting. 8. Flush the lines, healthy the motor, run it unloaded first, then at operating pressure at the same time as you watch temperature and noise. The usual mistakes are buying on the number “400” alone, accepting an “OMR 400” with no part number, and ignoring the series letters. FAQs What is the difference between a Danfoss OMR 400 dealer, supplier and distributor? A dealer sells to end users, a supplier is any seller of the part, and a distributor typically buys from the maker and supplies others. Check each claim. Is the Danfoss OMR 400 discontinued? One reseller lists it as no longer in production and replaced by the OMR X 400, 11185535. Ask any seller exactly what they’re offering. How do I know a Danfoss OMR 400 supplier is genuine? Get the part number, maker and a nameplate photo, then compare the datasheet. If in doubt, send the details to Advance Hydraulic Works. Is an OMS 400 or OMT 400 the same as an OMR 400? No. They’re different series with different displacements and ratings. Can Advance Hydraulic Works deliver a Danfoss OMR 400 alternative? Send the nameplate photos, part quantity and running stress to Advance Hydraulic Works and ask about availability, maker and assurance earlier than you devote. Your next step Photograph the nameplate, work out your expected speed, and send both to Advance Hydraulic Works. You’ll know exactly what you’re buying before you spend anything.
