We no longer sell Davey Pumps. Davey Pumps has closed their USA factory warehouse and we have had numerous warranty issues with their products that we could not resolve to our customer's satisfaction.
Davey Pump Pressure Booster 20 GPM 40 PSI boost 1 HP 230 Volt model # BT20-40 with Torrium controller and built-in pressure tank. Ideal for average to large two story homes or long runs of plumbing. Five water outlets can be operated at the same time without substantially reducing performance, assuming an average delivery of 3 GPM at 40 PSI and a 15 ft. suction lift. Replaces Davey HS18-40HTI This model is not yet Massachusetts Code or CSA approved.
Specifications:
The Torrium control starts the pump as soon as you switch on the tap and continues running until water is not required. The controller continuously monitors the flow of water and will switch it off to avoid damage if the supply becomes inadequate. The systems are compact, quiet and easy to install.
Applications Domestic water supply, pressure boosting from well or city, automatic water transfer.
Type of pump: Multiple stages ( 4 Impellers), self-priming centrifugal
Pump construction: 304 Stainless steel and corrosion-resistant materials.
Inlet & outlet: 1" FNPT X 1" MNPT(male pipe thread)
Cut-in pressure: Adapts to 80% of last shut-off head pressure
Maximum operating pressure: Cannot exceed 100 PSI
Tank size: Built-in spring loaded pressure tank overcomes the need for regular pressure vessels. The Davey BT Series does not require an additional pressure tank under normal operating conditions.See below External Pressure Tank Requirement:
Suction lift: Capable of up to 20 feet
Maximum inlet pressure: 24 PSI (Must install a pressure reducing valve on the suction side of the pump if the inlet pressure is more than 24 PSI)
Electrical: 230 volts, 1 phase, 5.0 Amps., 60 Hz, 1 HP, TEFC motor. Includes 6' electrical cord less plug
Maximum allowable city pressure: 24 PSI
Maximum water temperature: 150 degrees Fahrenheit
Carton Dimensions: 14.54" high, 17.4" long, 7.85" wide.

Must install a foot valve when pumping from a well or cistern. ORDER SEPARATELY
Do not exceed a total system pressure of 100 PSI.
The total system pressure will be the incomming city pressure plus the maximum output pressure from the data above.
Use a pressure regulating valve in the suction and /or discharge lines as required.
