Membrane pump head for a homogenizer or a high-pressure pump

Abstract

The disclosure relates to a membrane pump head for a homogenizer or a high-pressure pump. The membrane pump head comprises at least one pump head enclosed in a pump housing. The membrane pump head also includes a product chamber with inlet and outlet for the product, as well as a hydraulic chamber in which a piston is disposed to operate. The product chamber and the hydraulic chamber are separated by a double membrane. The membrane is oriented at 15-75° in relation to the longitudinal direction of the piston.

1 . A membrane pump head for a homogenizer or a high-pressure pump, comprising at least one pump head enclosed in a pump housing, the membrane pump head further including a product chamber with inlet and outlet for the product, and a hydraulic chamber in which a piston is disposed to operate, and the product chamber and the hydraulic chamber are separated by means of a double membrane, wherein the membrane is oriented at 15-75° in relation to the longitudinal direction of the piston. 
     
     
         2 . The membrane pump head as claimed in  claim 1 , wherein the membrane is oriented at 45° in relation to the longitudinal direction of the piston. 
     
     
         3 . The membrane pump head as claimed in  claim 1 , wherein a number of pump housings form a pump block, the pump block being held in union by means of tie rods. 
     
     
         4 . The membrane pump head as claimed in  claim 1 , wherein the membrane is manufactured from a thermoplastic. 
     
     
         5 . The membrane pump head as claimed in  claim 4 , wherein the membrane is manufactured from polytetrafluoroethylene. 
     
     
         6 . The membrane pump head as claimed in  claim 1 , wherein the membrane is manufactured from a metal.
