Component assembly for reconfiguring a centrifugal pump
First Claim
Patent Images
1. A component assembly for reconfiguring a centrifugal pump to a different type of centrifugal pump, comprising:
- back plate sized to be received adjacent an existing drive casing and to accommodate an existing drive shaft;
a new impeller of a type different from an original impeller of an existing pump, said new impeller being configured to register against said back plate and being structured for securement to the terminal end of an existing drive shaft of a centrifugal pump; and
a suction side cover having a central opening defining an inlet for a pump, said suction side cover being configured to accommodate said new impeller.

Abstract
A component assembly is provided for converting a conventional centrifugal pump, of the vortex impeller type for example, to a different type of centrifugal pump, such as a spiral impeller pump. The component assembly enables a resident centrifugal pump to be converted to a more efficient or appropriate type of industrial pump when conditions or application processing requirements change, and avoids the need to entirely replace an installed pump for a new type of pump.

11. A method for reconfiguring an existing type of centrifugal pump to a different type of centrifugal pump, comprising:
-
providing a centrifugal pump of a first type having a resident impeller and further comprising;
a drive side casing;
a drive shaft extending through said drive side casing;
a volute casing secured to said drive side casing;
a resident impeller received by and secured to said drive shaft; and
an existing suction side cover secured to said volute casing and sized to accommodate said resident impeller;
providing a component assembly for converting the centrifugal pump to a new type of centrifugal pump, comprising at least one of a back plate or an impeller adapter, and comprising a new type of impeller and a new suction side cover configured to accommodate said new type of impeller;
removing said existing suction side cover from said volute casing;
releasing said resident impeller from securement with said drive shaft;
positioning and securing at least one or either said back plate or said impeller adapter from said component assembly against said drive side casing and about said drive shaft and securing to said pump;
positioning said new impeller in registration against at least one of said back plate or impeller adapter;
securing said new impeller to said drive shaft; and
positioning said new suction side cover, configured to accommodate said new impeller, against said volute casing and securing said new suction side cover to said volute casing. - View Dependent Claims (12, 13)
