18 + 12 cc tandem: 18/12 ml/rev, 250 bar, anticlockwise (CCW). Flexible MOQ by model and order value; 1–2 pcs can be considered at a higher unit price.
The 18+12 ml/rev assembly is a two-section Deutz tandem pump. Its separate displacements matter when allocating hydraulic circuits; adding them into a single generic 30 ml/rev specification would lose the information an installer needs. The catalogue gives 250 bar, 3000 rpm, 24.0 L/min controlled flow and paired openings on each section.
The main identification for this entry is 18 + 12 cc tandem. The accompanying reference list is DEUTZ; compare the reference stamped on the removed body rather than relying on a generic seller photo.
No specific tractor serial ranges are established here for 18 + 12 cc tandem. Use the parts manual and existing hardware to complete the application check.
| Reference / model | 18 + 12 cc tandem |
|---|---|
| Product type | Tandem Hydraulic Gear Pump |
| Original reference numbers | DEUTZ |
| Applicable tractor models | Confirm from original pump / equipment parts list |
| Manufacturer reference | 18CC+12CC |
| Nominal displacement | 18/12 ml/rev |
| Maximum pressure | 250 bar |
| Rotational speed | 3000 rpm |
| Controlled flow rate | 24.0 L/min |
| Feed hole / connection | Ø20 & Ø20 |
| Discharge hole / connection | Ø15 & Ø15 |
| Rotation | anticlockwise (CCW) |
Two displacement figures (18/12 ml/rev) identify a multi-section pump. Before choosing a replacement, draw the existing hydraulic circuit and mark which outlet belongs to each stage.
Within the comparison set, 19 + 13 cc tandem lists 19/13 ml/rev and 250/200 bar. That is a useful limit check for the 18 + 12 cc tandem hydraulic request, not permission to alter the tractor’s original pump rating.
A separate controlled-flow line gives 24.0 L/min. Keep that figure distinct from an estimated geometric delivery based on displacement.
The stated speed is 3000 rpm. Before commissioning, verify the engine accessory drive ratio and that normal operating conditions do not exceed this listing.
As a sanity check, compare this entry with Deutz 19 + 13 cc tandem. A near-identical picture is weaker evidence than distinct OEM numbers, connection shapes and the stated CCW rotation.
Do not infer a warranty of interchangeability from an OEM number appearing in a search list.
The directional entry is CCW, viewed using the catalogue’s shaft orientation. A correct replacement should use the same viewing convention rather than assuming clockwise from the engine side.
A parts drawing should confirm the supply-side opening (Ø20 & Ø20) and the pressure-side opening (Ø15 & Ø15) with their centerline positions.

For a unit marked DEUTZ, compare the housing register and drive stub before connecting pressure lines. A distorted mounting face or damaged coupling should be corrected rather than forcing the new pump into place.
Before releasing the tractor to service, inspect both connections for seepage under the manufacturer’s safe checking procedure.
Please identify the tractor or engine installation for 18 + 12 cc tandem, together with the serial number if available. A sketch showing the Ø20 & Ø20 and Ø15 & Ø15 connections will shorten the matching process.
State whether you need one qualification unit before authorizing a production lot.
Compare the original identification marking with DEUTZ and measure the drive connection before selecting a replacement.
The comparison shows 19/13 ml/rev for the other part and 18/12 ml/rev here; rotation and mechanical interfaces must also be checked.
Order quantities are set according to pump type and total order value. A small order of 1–2 pieces can be considered at a higher unit price; new customers may request 1–5 samples when the item is suitable. Mixed-model orders are available, normally with a combined order value of approximately USD 1,500.
Typical production schedules are 10–25 working days for standard items, 20–45 working days for customized components, and 45–120 working days for project equipment. Usual delivery terms are EXW, FOB, CIF and DAP. FCA, CFR, CPT, CIP and DDP can be discussed for specific shipments. Confirm the final schedule and terms with the quotation.
