Combination Simplex/Duplex Alternating Full Voltage Pump Controller, 2HP 220V

A combination simplex/duplex alternating full voltage pump controller is a control panel that starts and stops one pump (simplex) or two pumps (duplex) directly across the line, at full supply voltage, without the ramp-up electronics of a variable frequency drive (VFD) or the reduced-voltage staging of a star-delta starter. For a 2.0 HP motor at 220V, 1-phase, 60Hz, full voltage (also called direct-on-line, DOL) starting is the standard approach: motors this small do not draw enough inrush current to justify the added cost and complexity of VFD or star-delta starting. In duplex configuration, the panel alternates which pump runs first on each cycle (lead-lag alternation), so wear is shared evenly between two pumps instead of one pump carrying the full duty cycle. This is the standard control method for twin-pump sump, sewage, and small transfer applications where redundancy matters more than speed control. If the lead pump fails to build pressure or trips on overload, this class of duplex controller typically brings the lag pump online automatically, keeping the system running until the failed unit is serviced. This is a distinct product from JOHOB's VFD duplex control panel line, which targets larger booster and building-water-distribution systems where variable speed reduces energy use and water hammer. A 2.0 HP, 220V, 1-phase, 60Hz full voltage simplex/duplex controller is sized for smaller, single-phase-fed sites: standalone buildings, small lift stations, and sites without 3-phase power available.

The controller covered on this page is rated for a single motor load of 2.0 HP, on a 220V, 1-phase, 60Hz supply, the standard single-phase service found at many small commercial and light-industrial sites across the Philippines outside of 3-phase-fed buildings. At this horsepower and voltage, full voltage (direct-on-line) starting is standard practice, so no additional soft-start or VFD hardware is required for the motor to start within typical utility voltage-drop tolerances. Panels supplied by JOHOB Hardware Trading for this class of control are sourced through an ISO 9001 certified partner factory, with CE marking on the electrical components. TUV SUD testing documentation is available on request for buyers who need it for facility compliance records. Exact enclosure rating, control voltage, float switch configuration, and alarm or annunciator options vary by application and are confirmed against your site's pump curve and wiring during the quote stage, since this product mixes several configurable elements (simplex vs duplex, alternation logic, alarm outputs, enclosure type) that a single published spec sheet cannot cover accurately. Send your pump nameplate data, supply voltage, and phase configuration and expect written confirmation of the exact panel specification within 1 business day.

A 2.0 HP, 220V, 1-phase, 60Hz simplex/duplex alternating controller fits sites where the pump load is modest and the power supply is single-phase, which rules out most large commercial buildings but covers a wide range of smaller Philippine sites. Typical applications include sump pump stations in basements and parking structures, small sewage ejector or lift station duty, booster duty for standalone buildings on single-phase utility service, and water transfer between small storage tanks where a backup pump is wanted for redundancy rather than speed control. Duplex alternation is the relevant feature for any of these applications where downtime is costly and a second pump is already installed or planned. Instead of running one pump to failure while a backup sits idle and untested, the alternating controller cycles duty between both pumps so both stay exercised and either can carry the full load if the other needs service. JOHOB Hardware Trading supplies this class of controller nationwide, covering NCR, Luzon, Visayas, and Mindanao, including PEZA and SBMA economic zones where zero-VAT treatment applies to registered locators and exporters. Standard lead time is 21 to 35 days ex-stock for common configurations, extending to 45 to 90 days for made-to-order panels with non-standard alarm, telemetry, or enclosure requirements.

JOHOB Hardware Trading does not publish list pricing for simplex/duplex alternating pump controllers, because the finished price depends on configuration (simplex vs duplex, alarm and annunciator options, enclosure type, float switch or pressure transducer control), certification documentation requested, and delivery location. Submit an RFQ with your pump's nameplate horsepower, voltage, phase, and site location, and expect a written quote within 1 business day. Two tax treatments apply depending on buyer status. VAT-registered buyers on the regular tax regime pay the standard 12% VAT. Buyers registered with PEZA or SBMA as locators or exporters qualify for zero-VAT treatment on the purchase, subject to the usual documentary requirements for zero-rated sales. Confirm your registration status with your quote request so JOHOB can issue the correct invoice type from the start rather than needing to reissue it. On lead time, standard configurations that match commonly stocked components ship in 21 to 35 days. Panels needing non-standard alarm outputs, telemetry integration, or other made-to-order elements run 45 to 90 days. Both timelines start from order confirmation, not from RFQ submission, so build the lead time into your project schedule once you have a signed quote rather than from the date you first inquired.

Choosing between a full voltage alternating controller and a VFD duplex panel comes down to motor size, power supply, and what you are trying to control. Full voltage (direct-on-line) control, the type covered on this page, is standard for small motors like the 2.0 HP, 220V, 1-phase, 60Hz case: the pump runs at a fixed speed whenever it runs, and the panel's job is starting, stopping, and alternating between two pumps. A VFD duplex panel, JOHOB's other pumping control product line, adds variable speed: the drive ramps pump speed up and down to match demand, which matters for larger booster systems that need to reduce energy use, control water hammer, or maintain constant pressure across a varying flow range. VFD panels in JOHOB's line start at 3 HP per pump on a 380 to 415V, 3-phase, 50Hz supply, a different power class than the single-phase 2.0 HP controller on this page. If your site has 3-phase power and a booster application where speed control saves meaningful energy, the VFD duplex panel is the better fit. If your site is single-phase, the motor is 2.0 HP or similarly small, or the application is simplex/duplex alternation for redundancy rather than speed control, the full voltage controller on this page is the correct and more cost-effective choice.
