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)

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.
