- Page 4 Hydronic Air Driven Pumps & Intensifiers 820 Installation, Use and Maintenance Booklet 1-4-2021 Installation Guide Pumps may be installed in a horizontal or vertical position for optimum functioning of suction and delivery valves. The round reservoir may be used horizontally and it is advised that the breather and sight glass be interchanged and/or the reservoir rotated to allow the breather to remain uppermost.
- Page 5 820 Installation, Use and Maintenance Booklet 1-4-2021 Application Hydronic air driven hydraulic pumps are designed for operating oil hydraulic circuits and to cover the widest range of requirements to the best advantage. The pump itself operates quite simply, using a known pressure intensification principle. A piston with a large surface area is actuated by compressed air.

- Page 7 P820 RATIO 1:30 P820 RATIO 1:40 For instance, when supplied with compressed air at 80 psi, the P820-5 will produce oil pressure of 80 x ratio, 400 psi. It should be remembered that actual efficiency produced by the pump is slightly less than given by the above theoretical calculation. This difference will not be noticed by a hydraulic gauge.
