Harp screens

 

Serpa-(Flex)-Harps consist of crimped screen wires arranged one after another building thereby square meshes. In order to achieve stability for the screens, the crimped longitudinal wires are linked at definite spacings by wires or PU bindings. The distances of the plastic bindings can be determinated specifically according to application. In vibrating screens, self-oscillations of the elastic screen wires are induced which prevent to a large extent blinding of the screen openings as well as the adhesion of screening material. The square mesh keeps firm and allows accurate screening. Production of harps is possible with round and flat wire.

Materials Wire: Spring steel, stainless steel

  • Application temperature: max. 80°C
  • Cross connections: PU, ss or spring steel
  • Max. screen width: 2500 mm
  • Alternative name : Isevier
  • Iserpalharfe
Veno-(Flex)-Harps

Veno-Flex-Harps consist of alternately arranged straight and crimped wires – crimped horizontally to the screen level. The straight and crimped wires form triangular screen openings. The screen wires are fixed at definite spacings by cross-bindings made of plastic bindings. The separation distances can be adapted according to requirements. This finish has the following advantages: Enlargement of the open screen area, an extension of service life and a reduction of adhesion of the screening material. In the case of the Veno-Flex-Harps, different vibrations arise in the screening process through the alternating crimped and straight wires. This enables clogging-free processing to a large extent, particularly in case of moist and sticky screening material.

Materials Wire: Spring steel, stainless steel

  • Cross connections: PU, ss or spring steel
  • Application temperature: max. 80°C
  • Max. screen width: 2500 mm
  • Alternative name : Iseveno

Harpa-(Flex)-Harps Harpa-Flex-Harps can be made out of smooth as well as of crimped longitudinal wires. These are fixed at definite distances through wires or PU bindings building by this long screen openings. Advantage: With the screening process, natural vibrations of the Harpa-Flex-Harps arise. Thereby a clogging of the screen openings and a sticking of screening material are prevented to a large extent. Further advantage of the Harpa-Flex-Harps is given by the plastic binding which enables to extend the service life of the harps in many cases.

Materials Wire: Spring steel, stainless steel

  • Cross connections: PU, ss or spring steel
  • Application temperature: max. 80°C
  • Max. screen width: 2500 mm
  • Alternative name: N-Harps
