Data sheet SPA/SPG pumps

Product catalog summary

Overview: This document provides technical specifications and operational guidelines for high-capacity gear pumps, specifically the SPA and SPG series, designed for working pressures up to 300 bar and displacements ranging from 0.9 to 61.1 cm³ per revolution.

Specifications:

Design: External gear pumps with flange mounting and threaded connections.
Materials: Housing made of aluminum or cast iron, with Teflon plain bearings.
Operating Conditions: Fluid temperature range from -15°C to +80°C, viscosity range from 10 cSt to 300 cSt, and recommended viscosity at 50°C is between 21 cSt and 46 cSt.
Filtration: Return line filtration with 10-25 µm mesh size is recommended, especially for higher operating pressures.

Operational Guidelines:

Drive Shaft: The coupling must allow axial movement to prevent axial forces on the pump shaft.
Pressure Definitions: Maximum continuous pressure is defined as pressure prevailing for more than 60 seconds, while peak pressure is allowed for a maximum of 5 seconds.
Mounting Position: The pumps can be mounted in any position.

Performance Data:

SPA Series: Available in various sizes with maximum speeds ranging from 2000 to 6000 rpm, and maximum continuous pressures up to 260 bar.
SPG Series: Similar specifications to SPA but with cast iron components, offering slightly higher pressure capabilities.

Ordering Information: The document provides a typology for ordering, including direction of rotation, drive shaft type, and construction type (SPA or SPG).

Additional Information: The document includes dimension and capacity data tables for different pump models, along with possible combinations for multiple pump configurations.

Displacement: 0,9 up to 61,1 cm3 / rev. Working pressures : up to 300 bar Allgemein / General 1) Die Angabe der Drehrichtung bezieht sich immer mit Blick auf die Antriebswelle. 2) Die Kupplung zwischen Pumpe und Antriebsmotor muG ein axiales Verschieben der Pumpenwelle ermoglichen, damit im Betrieb keine Axialkrafte auf die Pumpenwelle ubertagen werden. 1)Always look on the drive shaft. 2)The coupling between pump and motor has to allow an axial moving of the pump shaft, that no axial forces will be transmitted on the pump shaft.
