Product catalog summary
Overview: This document provides technical specifications and applications for SEM/VAC rotary piston vacuum pumps, which are part of the positive-displacement machines family. These pumps are used across various industrial sectors due to their high efficiency and capability to handle large volumes with minimal contamination.
Specifications: The SEM/VAC pumps feature symmetrical three-lobe pistons that rotate in opposite directions without surface contact, synchronized by high precision gears. They include an automatic overpressure valve for air recirculation to maintain thermal conditions and prevent extreme differential pressures. The document details models SEM VAC I and SEM VAC II, providing information on volume generated, vacuum limits, rotary speed, drive motor power, cooling water flow, and dimensions.
Model Details:
  • SEM VAC I: Offers a vacuum limit of 60 mbar and rotary speeds ranging from 2850 to 2915 rpm. The drive motor power varies from 1.5 to 7.5 kW, with cooling water flow between 75 to 155 lts/h.
  • SEM VAC II: Provides a vacuum limit of 5.10-2 mbar with two rotary speed options (A and B). The drive motor power ranges from 1.5 to 11 kW, and it can handle an admissible water vapor quantity of up to 12 Kg/h.
Applications: The combined system solutions are applicable in various industries, including serigraphy machinery, electric and electronic industries, packing and conveying plants, textile industry, printing plants, and more. They are also used in processes like drying, impregnation, degassing, distillation, evaporation, vacuum packaging, and spatial simulation techniques.
Contact Information: The headquarters are located in Astigarraga, Guipúzcoa, Spain. Contact details include phone, fax, website, and email for further inquiries.
Certifications: The document mentions certifications but does not provide specific details.

Las bombas de vacío de émbolos rotativos SEM/VAC pertenecen a la gama de máquinas de desplazamiento positivo. Los émbolos simétricos de perfil trilobular giran en sentido inverso sin contacto superficial, sincronizados mediante engranajes de alta precisión. Durante el proceso de rotación en fase de aspiración se genera un espacio de capacidad volumétrica creciente de caudal engendrado. Para controlar el grado de vacío y mantener las condiciones térmicas admisibles en servicio, la máquina dispone de una válvula automática de sobrepresión que permite la recirculación de aire evitando presiones...
