Abstract

Embodiments described herein provide systems and methods for high viscosity pumps including a noncompliant filter. One embodiment can include a multi-stage pump comprising an pump inlet flow path, a pump outlet flow path, a feed stage in fluid communication with the pump inlet flow path, a dispense stage in fluid communication with the feed stage and the pump outlet flow path, a noncompliant disposable filter for high viscosity fluid in a flow path between the feed stage and the dispense stage and a set of valves to selectively allow fluid flow through the multi-stage pump.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A disposable filter comprising:
 a head portion defining an inlet port, an outlet port and a vent port and sized and shaped to be compatible with a quick change manifold;   a bowl portion coupled to the head portion, the head portion and the bowl portion at least partially defining a filter cavity and forming a noncompliant filter housing;   a high viscosity filter cartridge disposed in the filter cavity, the filter cartridge having a filter cartridge outlet in fluid communication with the outlet port; and   wherein the disposable filter is adapted for use with a multi-stage pump for pumping high viscosity fluid.   
     
     
         2 . The disposable filter of  claim 1 , wherein the filter housing exhibits less than a 2 mL change in volume at 250 psi. 
     
     
         3 . The disposable filter of  claim 1 , wherein the filter housing exhibits less than a 1.5 mL change in volume at 250 psi. 
     
     
         4 . The disposable filter of  claim 1 , wherein the filter housing exhibits less than a 0.5 mL change in volume at 250 psi. 
     
     
         5 . The disposable filter of  claim 1 , wherein the bowl portion comprises at least one sidewall. 
     
     
         6 . The disposable filter of  claim 5 , wherein the at least one sidewall is at least 0.375 inches thick. 
     
     
         7 . The disposable filter of  claim 1 , wherein the bowl portion comprises a curved bottom portion. 
     
     
         8 . The disposable filter of  claim 1 , wherein the bowl portion comprises:
 an inner portion; and   an outer portion, wherein the inner portion and the outer portion form at least one sidewall of the filter cavity.   
     
     
         9 . The disposable filter of  claim 1 , wherein the disposable filter further comprises a reinforcing structure positioned to reduce compliance of the bowl portion. 
     
     
         10 . The disposable filter of  claim 1 , wherein the head portion comprises a curved top surface at least partially defining the filter cavity. 
     
     
         11 . The disposable filter of  claim 10 , wherein the curved top surface is angled upwards toward the vent port when the filter is installed. 
     
     
         12 . The disposable filter of  claim 11 , wherein the head portion comprises a set of ribs to reduce deflection of the top surface. 
     
     
         13 . The disposable filter of  claim 1 , wherein the head portion comprises a device identification portion shaped and sized to receive an identification device. 
     
     
         14 . The disposable filter of  claim 13 , further comprising a wireless identification device disposed in the device identification portion. 
     
     
         15 . A disposable filter comprising:
 a head portion defining an inlet port, an outlet port and a vent port and sized and shaped to be compatible with a quick change manifold, the head portion comprising:
 a curved top surface sloped towards the vent port; 
 a set of ribs to reduce deflection of the curved top surface; 
 a bowl portion coupled to the head portion, the bowl portion comprising:
 a cylindrical sidewall; 
 a curved bottom portion; 
 wherein top surface, sidewall and bottom portion define a filter cavity and wherein the head portion and bowl portion form a noncompliant filter housing; 
 
   a high viscosity filter cartridge disposed in the filter cavity and coupled to the head portion, the filter cartridge having a filter cartridge outlet in fluid communication with an outlet port of the head portion; and   wherein the disposable filter is adapted for use with a multi-stage pump for pumping high viscosity fluid.
