Overview

The DAB S4 5 GPM is a 4 in multi-impeller borehole pump for clean water, sold complete with a water-filled DAB Tesla motor. It lifts water from wells of 4 in diameter and up, or from tanks and cisterns, for homes, commercial buildings and garden or farm irrigation. Choose a 2-Wire build on the 4TW motor, which needs no control box, or a 3-Wire build on the 4GG motor with a separate control box. The same hydraulic end is listed on its own as the S4 pump end.

  • Sand resistant: technopolymer impellers in stainless steel adjustment rings.
  • Stainless hydraulics: liner, shaft, coupling, suction filter and cable guard in stainless steel; cast AISI 304 suction and discharge.
  • Built-in non-return valve, removable.
  • Water-filled Tesla motor with a removable CSA-approved cable connector.
  • VFD ready from 30 to 60 Hz.
What Ships and What It Needs to Run

Included: the S4 5 GPM pump end with its built-in non-return valve and a water-filled DAB Tesla motor, 4TW for 2-Wire builds or 4GG for 3-Wire builds, with its removable cable connector and lead, assembled as one complete pump.

4CBUS control box required on 3-Wire builds, ordered separately. The 4GG motor will not start without the DAB 4CBUS control box matched to its horsepower and voltage; the box for each build is in the table under Models & Performance. 2-Wire builds need no control box: the capacitor and thermal protector are inside the 4TW motor.

Drop pipe, drop cable and splice kit: sized to your setting depth and ordered separately.

Models & Performance — Will It Do What You Need?

Find your horsepower in the row. Total head is the depth to the pumping water level, plus 2.31 ft for every PSI you want at the tank, plus drop-pipe friction. The two output tables below do that sum for a 30/50 PSI pressure switch.

Total head in feet, by flow

HP 0 GPM (Shut-off) 1 GPM 4 GPM 5 GPM 7 GPM
0.5 HP 354 ft 346 ft 292 ft 256 ft 192 ft
0.75 HP 470 ft 452 ft 365 ft 332 ft 232 ft
1 HP 585 ft 549 ft 485 ft 439 ft 306 ft
1.5 HP 810 ft 800 ft 619 ft 549 ft 369 ft

DAB prints flow at each depth and discharge pressure rather than a head-at-flow table (S4 Technical Sheet 60191756, p. 4). Each head here is the highest total head, depth plus DAB’s own foot equivalent of the pressure, at which DAB prints at least that flow, so it never claims more than DAB’s grid. 0 GPM is DAB’s printed shut-off; 7 GPM is the highest flow every build reaches; DAB prints flows to 7-8 GPM by model.

As printed in the DAB S4 Technical Sheet (60191756), p. 4, at the 30 and 50 PSI rows. DAB’s figures exclude drop-pipe friction and are for a pump without check valve. — = DAB prints no figure there.

Before You Buy — The Limits That Decide the Fit
Well 4 in minimum diameter, or a tank or cistern
Water Clean and non-aggressive; sand up to 150 g/m³
Water temperature 32 F to 104 F
Motor wiring 2-Wire: no control box. 3-Wire: DAB 4CBUS control box required (table above)
Power 115 V on 0.5 HP only; every other build 230 V single phase

Installation Notes
  • Install vertically. Horizontal installation is possible; DAB recommends a cooling sleeve for it.
  • Allow no more than 20 starts per hour.
  • The Tesla motors run on a variable frequency drive from 30 to 60 Hz.
  • The motor lead plugs in through a removable cable connector, so a damaged lead is replaced without opening the motor.
