| 20110008194 | Electric Heating and Temperature Control for Process Pumps - Electrically heated pumps are disclosed that include electric heating elements that are linked to a process controller. The disclosed pump designs can be applied to packed seal, lip seal, mechanical seal and magnetic drive pumps. For packed, lip and mechanical seal pumps, the external jacketing on the pump, including the head, casing, pressure relief valve and bracket, can be replaced with electric heating elements, such as flexible or custom form membranes, attached to the pump through the use of adhesive or mechanical fastening devices. For the magnetic drive pump, the external jacketing on the pump head, pressure relief valve and casing can be replaced with electric heating elements attached to the pump through the use of adhesive or mechanical fastening devices. For the bracket portion of the magnetic drive pump, the external jacketing can be removed and the heating element is attached to the canister that contains the liquid and that is located between the inner and outer magnetic drive assemblies. Through the use of appropriately placed thermocouples in the head, pressure relief valve, casing, bracket, canister, etc., and a single or multi-channel on/off, proportional or PID controller, the heating zones may be linked together, monitored and controlled to the application requirements. The disclosed pump designs may also be applied to auxiliary equipment such as strainers. | 01-13-2011 |
| 20100000923 | Pump System for Deep Fryers Using Trans-Fat-Free Cooking Oil - A pump for use in a filtration process for a deep fryer is disclosed. The pump includes a drive shaft linked to a motor or motor drive shaft. The drive shaft passes through a seal assembly before passing into the pump chamber. The seal includes an outer seal housing that accommodates a lip seal. The lip seal is fabricated from PTFE. A combination oil filtration and supply system for a deep fryer is also disclosed that includes a motor linked to the drive shaft. The drive shaft passes through a supply pump and a filter/return pump. The supply pump includes an inlet in communication with a fresh oil reservoir and an outlet in communication with the filter/return pump. The filter/return pump includes an inlet in each communication with an oil filtration system and an outlet in communication with the outlet of the supply pump and an inlet to an oil distribution network. The oil distribution network includes a plurality of outlets, each in communication with an inlet of a vat. Each vat each includes an outlet in communication with the oil filtration system. The supply pump further includes a bypass valve that closes the inlet to the supply pump when flow from the fresh oil reservoir is cut off by closing a fresh oil supply valve. The bypass valve permits continuous circulation of fresh oil in the supply pump chamber and around the seal to prolong the life of the seal. | 01-07-2010 |
