Description
Spare parts set system SR820G is a dedicated service kit for maintaining and restoring the performance of compatible laboratory pump systems. It includes two zone membranes, four valve plates/seals, one O-ring D8×1.8, two O-rings D10×1.8, six O-rings D8×1.8 and two O-rings D28×2.65, covering the principal wear components that ensure leak-tight operation. Regular replacement of these membranes, valve plates and O-rings helps preserve pumping efficiency and chemical resistance under typical laboratory conditions. The complete set is supplied by manufacturer KNF as a single unit, simplifying inventory and ensuring that all required seals are available at the moment of service. Components are dimensioned specifically for the SR820G system, guaranteeing proper fit and reliable sealing when fitted correctly. This kit is particularly useful for laboratories running continuous or high-duty-cycle diaphragm pumps that demand original-specification spare parts for consistent analytical results.

Questions about SPARES-KIT SYSTEM SR820G
What is this article?
SPARES-KIT SYSTEM SR820G is the article on this page. Luminix Health distributes KNF for laboratory use. It sits in Half & full-face respirators, inside Respiratory protection, in Lab safety equipment.
A half-mask covers nose and mouth. A full-face mask adds the eyes and takes the same cartridges in a larger body. The cartridge, not the rubber facepiece, chooses the hazard. The mask has to be the size that seals, which is a fit test, not a guess from a shirt size.
A respirator filters the air the person breathes, or supplies other air. An FFP mask is a particle filter worn on the face. A half-mask or a full-face mask takes cartridges, and the cartridge is chosen for the gas or the particle. The mask that is not sealed to the face does not filter. Fit is part of the product. Standards are listed under ISO respiratory protection. The rule is the PPE Regulation. Workplace practice is EU-OSHA.
