Internal gear pumps EIPS1

Product catalog summary

Technical Specifications:
The document provides detailed specifications for internal gear pumps with rated sizes ranging from 016 to 050. The specific volume varies from 1.6 to 5.0 cm³/rev. Continuous operating pressure is specified at 300 bar for size 016 and 250 bar for sizes 020 to 050. Peak operating pressure for a maximum of 10 seconds at a 15% duty cycle is 320 bar for size 016 and 300 bar for sizes 020 to 050. The cut-in pressure peak for 100 ms is 350 bar. Maximum speed is 4,000 min^-1, with a nominal speed range of 400 to 3,600 min^-1. Operating viscosity ranges from 10 to 300 mm²/s, with a starting viscosity of 2,000 mm²/s. Operating temperature ranges from -20°C to +100°C, with medium temperatures from -40°C to +120°C and ambient temperatures from -40°C to +80°C. The maximum admission pressure on the intake side is 2 bar absolute, and the minimum is 0.8 bar absolute (0.6 bar at start). Filtration is required to be Class 20/18/15 according to ISO 4406, and the life expectancy is not less than 1 million cycles against peak operating pressure.

Design and Ordering Information:
The pumps are available with a SAE/AA-2-hole flange and cylindrical shaft or with an Oldham coupling. Dimensions for each size are provided, detailing measurements such as A, B, C, D, E, F, G, and H for the flange type, and additional I for the coupling type. The document includes ordering examples for both configurations.

Additional Notes:
The pumps do not have corrosion protection, and the maximum permissible values should not be applied cumulatively. The document emphasizes that all data serve solely for product description and are not legally binding characteristics. Contact information for Eckerle Technologies GmbH is provided for further inquiries.
