GEAR PUMP "PG" SERIES

End plate Features

DEFINITION OF PRESSURES

P3 = Peak pressure P2 = Intermittent operating pressure (1/3 of working time) P1 = Continuous operating pressure

max. 20 s

GENERAL

Superior performance and reliability in heavy-duty hydraulic application. Construction with large area, low-friction bushings provide strength, high efficiency, and long life in severe operating environments. The design includes an advanced thrust plate and seal configuration,which optimizes performance even in high temperature and low viscosity conditions. Double pump with common suction reduces mounting costs, allow for a small package size.

WORKING CONDITIONS

- Pump inlet pressure (absolute pressure) - Minimum operating fluid viscosity - Max starting viscosity - Suggested fluid viscosity range - Fluid operating temperature range - Fluid operating temperature range with FPM seals(Viton) - Hydraulic fluid

0,7 to 2,5 bar 10 to 36 psi 12 mm 2 / sec 800 mm 2 / sec 17 - 65 mm 2 / sec - 15 to 85 °C - 20 to 110°C mineral oil

Important: in case of assembling of pumps without shaft seals, you have to keep the value of min. suction pressure ( 0.7 bar (abs)) in the vane between pump and coupling too. Lower pressure can lead to suction of oil through the front flange (seat of the shaft without seal); this can damage seriously the pump.

In case of need we can supply the flange with a threaded hole to vent the drain of the shaft seals area. As you can see on pages 10 and 11, the flanges are: S7 with G1/8 threaded hole S8 with SAE4 threaded hole

HYDRAULIC PIPE LINE

To ensure favorable suction conditions it is important to keep pressure drop in suction pipe line to a minimum value (see WORKING CONDITIONS). To calculte hydraulic pipe line size, the designer can use; as an approximate guide, the following fluid speed figures:

From 1 to 2 m/sec on suction pipe line From 6 to 10 m/sec on pressure pipe line

From 3.28 to 6.36 ft/sec on suction pipe line From 19.7 to 32.8 ft/sec on pressure pipe line

The lowest fluid speed values in pipe lines is recommended when the operating temperature range is high and/or for continuos duty. The highest value is recommended when the temperature difference is low and/or for intermittent duty.

DESCRIPTION OF THE NEW PRODUCT IDENTIFICATION LABEL

Based on the firm certification ISO 9001 - UNI EN 29001, section 4.8 (identification and tracebility of the product), we have adopted a new identification label starting from the 1st march 1995. Pls, see following example:

A B C E F D G

Only for pumps 2PB and 2PZ (except triple 2PB) the identification product is marked on the top of the pump body as shown here below:

A = Product short descritpion (eg. VD8A/FDD/U4G). B = Customer part number. C = Salami part number (eg. 6235 0025 0). D = Production code (for Salami management) E = Rotation sense (only for pumps). F = Production date (see data sheet here below) G = Progressive number of assembling.

SALAMI 09/02 MADE IN ITALY 4010998 612271211 nr. 13 2PB 19S B25 B5

Product short description. Salami part number and progressive number of assembling. Production code (for Salami management). Mounth and year of made: maybe in the future you can find this type of production date in the label beside too. Rotation sense.
