1. Model Code Breakdown (Typical)

· 109 – VIS series motor (gerotor design)

· 1119 – Base model, corresponding to a displacement of 40.6 cm³/rev (VIS 40)

· 006 – Configuration code, usually indicating:

· Shaft: 1 inch straight shaft with parallel key

· Mounting flange: SAE A 2-bolt flange (pilot diameter 82.55 mm)

· Ports: Side standard ports (commonly G 1/2 or SAE 8)

2. Technical Specifications (Typical VIS 40 values)

Item Metric Imperial

Displacement 40.6 cm³/rev 2.48 in³/rev

Max. continuous pressure 140 bar 2030 psi

Max. intermittent pressure 175 bar 2540 psi

Peak pressure 210 bar 3045 psi

Max. continuous torque approx. 92 Nm 814 lb-in

Max. intermittent torque approx. 115 Nm 1018 lb-in

Max. continuous flow 30 L/min 7.9 US gpm

Max. continuous speed approx. 730 rpm –

Max. output power approx. 7 kW 9.4 hp

Weight (approx.) 5.9 kg 13 lb

Note: Speed and flow are theoretical values without back pressure. Actual allowable speed may be slightly lower depending on back pressure and oil temperature.

3. Structure and Interfaces

· Motor type: Gerotor motor, shaft distribution valve, high volumetric efficiency, strong contamination tolerance.

· Mounting flange: SAE A 2-hole (bolt hole pitch 106.4 mm, pilot diameter 82.55 mm).

· Output shaft: Straight shaft, diameter 1 inch (25.4 mm), effective length approx. 63 mm, with 1/4 inch square key.

· Ports: Side arrangement; common thread sizes are G 1/2 (BSPP) or 7/8-14 UNF (SAE #8), with O-ring seal.

· Drain port: VIS series typically has no external drain line; internal drain occurs through the gerotor cavity (confirm actual configuration).

4. Typical Applications

This medium-displacement VIS motor is widely used in applications requiring low speed, high torque and a compact envelope, such as:

· Agricultural machinery (sprayers, hose-reel irrigation systems, augers)

· Side brush drives on industrial sweepers, scrubber drives

· Small winches and sprocket drives

· Conveyor belts, mixers, auxiliary drives for crushers

· Replacement or repair of older Char-Lynn S series / H series motors in the medium displacement range

5. Additional Notes

· This motor has a long production history. Currently, Eaton may have incorporated it into the VIS 40 standard product line; 109-1119-006 remains an orderable valid part number or may have been superseded by a new one.

· To order or verify a replacement model, provide the complete number to an Eaton distributor, or refer to the latest Eaton Char-Lynn VIS motor catalog (E-MOLO-MC001-E1).

· When using it as a service replacement, always check that the shaft extension dimensions, mounting flange pilot diameter, and port thread type are exactly the same to avoid installation problems.
