• Type: External gear pump
• Displacement: 80.5 cc/rev
• Max. pressure: 25 bar rated (40 bar test pressure)
• Speed range: 200 – 3000 rpm
• Rotation: Clockwise (CW) / Counter-clockwise (CCW) available
• Mounting: Square 4-bolt flange (SAE / DIN standard)
• Port size: SAE 2″ 4-bolt flange, side ports
Send us your pump model or a photo of your sample, and we’ll confirm the match.
When a customer asks for a KF80 replacement, the useful starting point is the pump being removed and the service it must resume. Send the complete nameplate marking, including any additional suffix, with photographs of the shaft end, mounting flange and both connections. If the nameplate is damaged, include every readable character and the available installation drawing. A distributor can then keep the technical inquiry linked to the customer’s repair order instead of relying on a shortened stock description.
Compare the shaft diameter and key, shaft projection, flange location, mounting dimensions, port arrangement and clearance around the relief valve. Show existing adapters and modified pipework in the photographs. Those details matter when a repair shop needs a pump that fits the installation without unexpected changes. A shared KF80 size designation is only the beginning of that comparison; the complete configuration and actual interfaces determine what belongs on the order.
For a pump already judged uneconomical to repair, request a complete-unit price alongside the repair option and include any installation changes in the comparison. Where diagnosis is still open, pass on the maintenance findings and fluid, inlet and drive conditions. The product offered here carries POOCCA branding. Keep that identity clear in the quotation you pass to your customer, particularly when the original inquiry names a KRACHT pump.
RF7-D15 describes choices that affect the replacement decision. R means clockwise rotation viewed from the pump shaft end; the catalog shows left-to-right flow in that viewpoint. Establish that view before comparing the motor direction and connections. F identifies a DIN flange without an outboard bearing. A drive that imposes external shaft loads therefore needs particular review: the radial-load allowance for a bearing-supported alternative cannot be carried over to F, and the catalog does not allow axial shaft forces.
Sealing code 7 specifies a double radial lip-type shaft seal in FKM. Keep the original seal code in a replacement inquiry because a different code may change the sealing arrangement or material. The standard KF63/80 catalog connection is SAE 1½ inch, while a separately identified 2-inch alternative also exists. Select the matching connection drawing and compare the shaft fit, flange and valve projection together. This gives the repair technician a meaningful fit check and gives the buyer a configuration reference to retain for the next order.
| Code | Meaning | Selection detail |
|---|---|---|
| KF | External gear pump family | Catalog reference design |
| 80 | Nominal size 80 | 80.50 cm³/rev geometric displacement |
| R | Clockwise rotation | Viewed from the pump shaft end |
| F | DIN flange | Without outboard bearing |
| 7 | Double radial lip seal | FKM sealing reference |
| D15 | Adjustable relief valve | 0–15 bar range; actual setting to specify |
CATALOG REFERENCE · EXACT SUPPLIED DUTY TO CONFIRM
| Characteristic | Reference value | Applies with these conditions |
|---|---|---|
| Geometric displacement | 80.50 cm³/rev | KF80 row; nominal size and geometric displacement differ. |
| Speed envelope | 200–3000 rpm | Catalog range; filling, viscosity, pressure and drive conditions apply. |
| Relief-valve range | 0–15 bar | D15 adjustment range, not a verified factory setpoint. |
| Rotation | Clockwise | R code; defined looking at the shaft end. |
| Mounting | DIN flange | F version without outboard bearing. |
| Shaft-seal arrangement | Double FKM lip seal | Code 7 catalog interpretation; supplied construction to confirm. |
| Base-pump pressure limit | 25 bar, conditional | Base-pump reference only. Do not use this as the assembled D15 rating. |
A pump that suits warm oil still needs an appropriate starting condition. State viscosity at the coldest expected start as well as at normal operation. The fluid needs minimum lubricating properties, no solids and compatibility with the selected materials. Complete filling depends on viscosity, speed and the inlet arrangement. The catalog’s normal lower inlet-pressure boundary is −0.4 bar gauge; −0.6 bar is only a brief start-up allowance, such as for a cold start. These figures describe inlet conditions. A pressurized inlet also needs review against the seal’s speed-dependent limits.
D15 identifies an adjustable relief range of 0–15 bar, with the actual setting to be specified for the order. The pump-mounted D valve is for brief overflow during short-term overpressure events. If the circuit regularly diverts flow, an appropriate external relief or return-to-tank arrangement is needed because prolonged internal bypass can overheat the pump. Include expected overflow duration and frequency in the inquiry. The conditional 25-bar catalog limit for the KF80 base pump does not establish a 25-bar operating rating for this D15 assembly.
Specify the required relief setting and brief-overflow duty with the inquiry. A process that normally bypasses flow needs a suitable separate return-to-tank arrangement.
For a single repair order, send the complete model information, required quantity, delivery destination and the customer’s target date. For distributor replenishment, identify the exact configuration for each line and the quantity being compared. Ask for unit price, currency, included accessories, delivery terms and the proposed dispatch date. Stock status and lead time should relate to that specific item and quantity; a general product listing does not establish availability.
Make the required quality and purchasing documents part of the inquiry. These may include an agreed dimensional drawing, material or seal documentation, a recorded relief setting and specified performance acceptance results. State the documents your customer needs and have their availability and scope addressed in the quotation. Warranty, inspection and other commercial terms also belong in the written offer rather than being assumed from the product name.
For repeat resale or OEM orders, retain an approved configuration record covering the full type code, drawing revision, connection option, relief setting and operating duty. Agree sample acceptance and how later changes will be handled before treating a previous order as the supply reference. Quantity breaks, batch documentation and packaging requirements can be included in the quotation request. This helps a distributor preserve the customer’s approved specification across separate repair jobs or replenishment
It is a replacement candidate when the complete configuration, installation interfaces and operating duty match. Send the original model marking, nameplate photograph, shaft and flange details, port photographs and any installation drawing. Confirm the proposed supplied dimensions and requirements before approving it for your customer’s equipment.
The offered product is POOCCA-branded. The KRACHT catalog is used as a technical reference for configuration comparison. It does not establish original KRACHT manufacture or measured performance of the supplied product. State any original-brand or origin-documentation requirement in your inquiry.
Do not assume they are interchangeable. Code 7 specifies a double FKM radial lip-type shaft seal. Compare the complete original code, sealing arrangement, fluid compatibility and installation requirements. A shared KF80 size, rotation or flange designation does not establish replacement compatibility.
Using the catalog geometric displacement of 80.50 cm³/rev, the ideal geometric calculation is approximately 116.73 L/min before operating losses. The original catalog lists 110 L/min at 1450 rpm and 10 bar with mineral oil at 34 mm²/s, with +10%/−5% tolerance. These are catalog references; specify your working conditions and any required supplied-unit performance verification.
D15 identifies an adjustable relief range of 0–15 bar, rather than a confirmed factory setting of 15 bar. Specify the required setting in the order. The valve is intended for brief overflow during short-term overpressure events, rather than continuous bypass or flow regulation.
Provide the complete model, quantity, delivery destination and required date. For replacement orders, include the old pump’s nameplate, shaft, flange and connection details. For new equipment, add the fluid, operating temperature, speed, required flow and relief setting. Include any drawing, packaging, inspection or documentation requirements so the quotation can address your customer’s order.
