Product catalog summary
Overview: This document provides technical specifications and performance data for the KNF NP40 series pumps, specifically the NP40KPDC VA and NP40KPDC-BI4 VA models. These pumps are designed for precise and stable gas delivery with low pulsation and high reliability.
Performance Data:
  • Material Design: Pump head made of PPS, diaphragm and valves/sealing made of EPDM.
  • Flow Rate: 3.7 l/min at atmospheric pressure for both models.
  • Ultimate Vacuum: 210 mbar abs.
  • Pulsation: 18 mbar, which is a 93% reduction compared to versions without an integrated damping chamber.
  • Temperature Range: Permissible media and ambient temperature is +5º C to +40º C (41º F to 104º F), with extended temperature options available on request.
  • Weight: 214 g (7.55 oz) for NP40KPDC VA and 208 g (7.34 oz) for NP40KPDC-BI4 VA.
Electrical Data:
  • Voltage Options: 12V and 24V for both models.
  • Motor Type: Integrated brushless DC motor.
  • Current (Imax): 0.59 A (12V) and 0.29 A (24V) for NP40KPDC VA; 0.68 A (12V) and 0.37 A (24V) for NP40KPDC-BI4 VA.
Advantages:
  • Low pulsation for smooth flow.
  • Customizable and tested to customer specifications.
  • High reliability and excellent size-to-performance ratio.
  • Low vibration and uncontaminated transfer.
  • Long service life and maintenance-free.
Applications: Suitable for medical devices, analytical equipment, emission measurement, reprographic, safety/security, and food industry.
Options and Accessories:
  • Various motor and eccentric options available on request.
  • Spare part kits and accessories like silencers and mounting plates are available.
Digital Customization: The pump can be adapted to customer systems through firmware parameterization of the integrated brushless motor.
Important Notes: Performance values are determined under test conditions and may vary based on application and system parameters. Operating instructions and safety information should be reviewed before use. KNF reserves the right to make changes without notice.

Mounting plate Robber-bonded metal Hole distance 43 x 22 mm. Inner diameter of the sleeve is 3.5 mm, screws are included. SPARE PARTS DIGITAL CUSTOMIZATION Thanks to digital technology, this pump can be quickly adapted to the customer's system. This is done by parametrizing the firmware of the integrated brushless motor at KNF. The performance values for the series models shown on this data sheet were determined under test conditions. The actual performance values may differ and depend in particular on the usage conditions and therefore on the specific application, on the parameters of the components...
