Italian ATOS gear pump PFG-187/D in stock

Brand

ATOS/Italian Atos

The following precautions should be taken when using ATOS gear pumps:

(1) The pump drive shaft and the prime mover output shaft should be installed using a flexible coupling with a coaxiality deviation of less than 0.1mm. For shaft sleeve couplings, the coaxiality deviation should be less than 0.05mm.

(2) The transmission device should ensure that the pump's drive shaft is under stress within the allowable range.

(3) The pump's suction height should not exceed 0.5m.

(4) A mesh filter is usually installed at the pump's suction port, with a filter accuracy of less than 40μm. The filter installed on the system's return oil line should ideally have an accuracy of less than or equal to 20μm.

(5) The working oil should be strictly selected according to regulations, with a working temperature range of -20～80℃.

(6) The pump's rotation direction must be correct, i.e., the pump's inlet and outlet positions must be correct. Disassembly and assembly of the pump must be strictly performed according to the manufacturer's instruction manual. (7) Tighten the screws on the pump inlet and outlet pipe joints. Ensure the sealing devices are reliable to prevent cavitation and oil leakage, which would affect pump performance. Avoid starting the pump under load and stopping it under load.

(8) Before starting, check that the relief valve (safety valve) in the system is at its set permissible pressure.

(9) For new pumps or overhauled hydraulic pumps, perform no-load operation and a short period of overload operation before use. Then check the pump's operating condition; no leakage, impact noise, excessive heat, or excessive noise is allowed.

(10) If the pump is not used for a long time, disconnect it from the prime mover. When using it again, do not immediately use the maximum load; allow at least 10 minutes of no-load operation. ATOS gear pump Shanghai general agent in stock:

When installing an ATOS gear pump, the following precautions should be taken:

1. Conduct a detailed inspection of all components; all should meet the corresponding standards.

2. The perpendicularity of both end faces of the gears to the shaft centerline and the parallelism of both end faces of the gears should be qualified; the gear meshing should be good.

3. The shaft diameter should meet the technical requirements, and the coaxiality of the bushing or bearing with the shaft diameter should be qualified.

4. The gear end face clearance should be adjusted appropriately.

5. When tightening the end face bolts, the force should be symmetrical and even; tighten while rotating the rotor. If jamming occurs, loosen the bolts and retighten.

6. When adding packing and tightening the gland, tighten while rotating the rotor; do not overtighten.
