Battery backup sump pump quotes compared on one electrical and quantity basis
Hold motor supply, DC backup scope, quantity and accessories still while you read factory prices. This page is a comparison method, not a discount table.
What same-basis means for a battery backup sump pump
Centrifugal Pump Sourcing lines up factory quotes. We do not publish a market index or a savings percentage. A battery backup sump pump is usually a second machine in the same pit: a DC motor, a charger and a battery, with a flow curve that is not the AC pump's curve. If one offer is an AC pump with a charger kit and another is a complete DC backup set, the prices are not about the same scope. Port sizes, housing material and control/float arrangement explain many gaps that look like "price" at first glance.
Electrical sameness is written, not assumed. State AC supply for the primary pump in V, phase and Hz, and state the DC voltage of the backup motor as the factory states it. Current stays in A. Do not drop a kA interrupting number onto this comparison unless a listed combination was requested and both factories quoted that combination. Motor power on the AC side is HP or kW as printed; we will not convert one into the other to force a match. If the specification moves—different basin diameter, different discharge, different battery amp-hour rating—the set has to be re-quoted. Old numbers do not travel.
Comparable
- Stated model, AC ratings, and DC backup voltage on the same revision
- Flow at a named head for both the AC pump and the backup pump
- Quantity, packing and requested delivery terms
- Which of basin, check valve, float, charger and battery sit on the line item
Not comparable
- Unstated test conditions or a maximum-flow figure with no head
- Different enclosure, port size or float arrangement left unnamed
- A series listing used as if it were the offered model's file
- Any market price percentage or "cheaper than usual" claim
NEMA enclosure type and IP rating, if a cover is quoted, stay in the factory's wording. Ingress protection is not translated into a NEMA type on this page. Coil voltage on a control accessory is a line item when that accessory is included. SCCR, selective coordination and residual current device settings stay with the building electrical design. Inquiry options are on products. Basin and float language is in the basin article. Duty-point pairs are in the duty point note. Send a request through contact.
