APPLICATIONS

Dos­ing pis­ton for use in dosers for filling/ bot­tling of food­stuffs in liquid to paste form

CHARACTERISTICS

  • All the func­tions – pumping/displacing, scrap­ing and seal­ing – are com­bined in a single component 
  • The integ­ral con­struc­tion provides a com­pletely smooth sur­face without gaps 
  • Wide product and tem­per­at­ure spectrum
  • PTFE com­pound ver­sion for SIP (Ster­il­iz­a­tion In Place) pro­cesses, not suit­able for highly abras­ive products 
  • Low fric­tion 
  • Avail­able in any dia­met­er from 12 mm to 70 mm (lar­ger dia­met­ers on request)

Advant­ages Lip Piston

  • Sig­ni­fic­antly improved cleanab­il­ity com­pared to nor­mal slid­ing ring 
  • Easy change of wear­ing parts 
  • Hygien­is­cher O-Ring Ein­bauraum in Anlehnung an DIN 11864

TEMPERATURE RANGE

From +5 to +150 °C.

Extreme altern­at­ing tem­per­at­ures dur­ing the filling oper­a­tion should be avoided due to thermal expan­sion of the plastic.

MATERIALS

IDG mater­i­al

  • 26A stand­ard material
  • 31K lower fric­tion, reduced abra­sion resistance

Design inform­a­tion for hous­ings with auto­mat­ic cleaning

For SIP (Ster­il­iz­a­tion In Place), the MANOY® AS dos­ing pis­ton is fed into the wash­ing hole, which must be designed so that the pis­ton has suf­fi­cient expan­sion capa­city dur­ing SIP at +140°C to avoid dam­aging its func­tion­al­ity and short­en­ing its life.

After the clean­ing pro­cess the MANOY® AS dos­ing pis­ton may only be moved into the dos­ing hole when a tem­per­at­ure close to the oper­at­ing tem­per­at­ure (oper­at­ing tem­per­at­ure +20 °C), and not to exceed +80°C, has been reached.

A feed cone into the dos­ing hole of 10° max. and roun­ded edges are essential.
