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.
Claims15
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.
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.
