| 20100166570 | METHOD AND APPARATUS FOR DETECTING THE FLUID CONDITION IN A PUMP - A pump control system which detects a fluid condition in a pump is disclosed. The pump control system may include a control event based on the fluid condition in the pump. The pump control system may detect a fluid condition in the pump by monitoring the frequency response of the pump. | 07-01-2010 |
| 20100154534 | METHOD AND APPARATUS FOR CAPACITIVE SENSING THE TOP LEVEL OF A MATERIAL IN A VESSEL - A method and apparatus for sensing the top level of a material in a vessel is disclosed. A method and apparatus for sensing changes in the top level of a material in a vessel is disclosed. | 06-24-2010 |
| 20090226329 | Condensate Pump - A condensate pump that provides a ventilation system that efficiently expels warm air surrounding a pump motor is disclosed. The pump has a motor-driven fan, a cover that encloses the fan, and a ventilation opening that allows for air to enter through the cover. The cover has an exhaust opening adjacent to the fan and a discharge outlet. The space between the exhaust opening and the discharge outlet defines a throat. A cutwater is adjacent to the exhaust opening for focusing air outward through the throat and expelling it from the cover through the discharge outlet. | 09-10-2009 |
| 20090129939 | Apparatus for thermal dissipation and retention of float - In an improved pump assembly having a fluid reservoir into which a stationary post extends, a sensor is supported by the post and a floating member is supported for travel between upper and lower portions of the post. A magnet is supported by the floating member, the sensor responding to the position of the magnet as the floating ring member moves along the post. A float retention member is detachably supported by the post to retain the floating member on the post, the floating member having a support ring with a plurality of inwardly extending spring members disposed to grip the end of the post. A heat exchanger is supported for absorbing a portion of the thermal energy created by the pump assembly. | 05-21-2009 |
