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

A combination simplex/duplex alternating full voltage pump controller is a control panel that starts one pump (simplex) or two pumps (duplex) directly across the line, at full voltage, without a soft-start or variable frequency drive stage. In duplex configuration, the panel alternates which pump leads and which stands by on each start cycle, or on each pressure or level signal, so wear is shared evenly between both units instead of one pump running continuously while the second sits idle. If the lead pump trips or fails to build pressure within its set time, the duplex logic brings in the standby pump automatically, so a single pump fault does not shut down water supply to the building. This is the simplest and lowest-cost way to run two pumps in a lead-lag arrangement, and it remains the standard choice for smaller booster and transfer pump sets where the extra cost of a VFD duplex panel is not justified by the flow variation on site. JOHOB Hardware Trading supplies this controller rated specifically at 2.0 HP, 220V, 1-phase, 60Hz, the common motor rating for small to mid-size commercial buildings, condominiums, and light industrial sites running on single-phase power. The panel is sized to the motor nameplate current so the overload protection trips at the correct threshold, protecting the motor from sustained overcurrent. For sites where flow demand varies significantly through the day, or where energy cost per kWh matters more than upfront panel cost, see our guide on VFD duplex panels below.

The controller covered on this page is rated 2.0 HP output, for a motor drawing power from a 220V, single-phase, 60Hz supply, the standard utility service found in most Philippine commercial and residential buildings outside large industrial sites on 3-phase feeds. Core components in this class of panel typically include a main circuit breaker or fused disconnect sized to the motor's full-load amperage, a magnetic contactor per pump for full-voltage direct-on-line starting, thermal overload relays for motor protection, an alternator relay or timer to swap lead/lag duty between the two pumps in duplex mode, Hand-Off-Auto selector switches per pump for manual override during maintenance, and pilot lights or a digital display showing pump status and fault conditions. The enclosure is specified to the installation environment, indoor dry locations versus outdoor or wash-down areas, since enclosure rating affects both cost and service life. JOHOB Hardware Trading confirms exact breaker size, wire gauge, and enclosure rating against the specific pump motor nameplate and site conditions at RFQ stage, since a controller sized to nameplate current is what protects the motor and keeps the installation compliant.

A 2.0 HP, 220V, single-phase simplex/duplex full voltage controller fits pump loads common across Philippine commercial and light industrial buildings: domestic water booster sets in small to mid-rise buildings, sump and dewatering pump pairs, transfer pump sets moving water between storage tanks and overhead tanks or hydropneumatic systems, and jockey or make-up pump duty on utility systems. JOHOB Hardware Trading supplies this controller as part of a broader Pumping and Pressure Systems line that includes booster, transfer, and submersible pumps alongside VFD duplex panels for larger or flow-variable installations, so a buyer standardizing on one supplier for the full pump-and-panel package has a single point of contact for both. Coverage is nationwide: NCR, wider Luzon, Visayas, and Mindanao, including PEZA, SBMA, and Clark-registered facilities where import and VAT treatment differ from standard commercial accounts. Because the panel pairs with pumps already in our catalog, such as transfer and submersible pumps, buyers replacing an existing single-pump setup with a duplex lead-lag arrangement can source the controller and a matched second pump from the same quotation instead of coordinating two separate vendors.

JOHOB Hardware Trading does not publish a fixed list price for this controller, or for any panel, because the final price depends on breaker size, enclosure rating, indicator and metering options, and current material and freight cost at the time of order. What we can commit to upfront: a response to your RFQ within 1 business day, and a standard lead time of 21 to 35 days ex-stock for panels built from components already on hand, or 45 to 90 days for made-to-order configurations requiring non-stock breakers, enclosures, or custom panel layouts. On tax treatment, standard commercial accounts are billed with 12% VAT. Buyers registered with PEZA or SBMA, and export-oriented enterprises qualifying under their respective incentive schemes, are billed at zero-VAT on presentation of the required certificates, which our sales team will confirm applies to your account before the formal quotation is issued. To get an accurate number, send us the pump motor nameplate (HP, voltage, phase, full-load amps), simplex or duplex configuration, and enclosure environment (indoor or outdoor, wash-down or dry), and we return a firm, itemized quotation, not a range, within 1 business day.

A full voltage alternating controller and a VFD duplex panel solve the same lead-lag problem, running two pumps with automatic standby, but they differ in how the pump starts and runs. Full voltage control applies line voltage to the motor at start, which is simpler and lower cost but produces a hard start: full inrush current and full mechanical torque the instant the contactor closes. A VFD duplex panel ramps the motor up to speed gradually, cutting inrush current and start-up mechanical stress, and can also modulate pump speed continuously to match demand rather than running the motor at full speed whenever it runs at all. That speed modulation is where a VFD panel earns back its higher upfront cost: on systems with significant flow variation through the day, running the pump at reduced speed for most of that variation uses less energy than cycling a full-voltage pump on and off at full speed. For a fixed, steady load such as a dewatering sump or a small booster set with limited demand swing, the energy-saving case for a VFD is weaker, and a full voltage duplex controller reaches the same lead-lag reliability at a lower installed cost. JOHOB Hardware Trading supplies both configurations and sizes each against the actual flow profile of the site rather than defaulting to one or the other; see our VFD duplex control panel product page and our VFD sizing guide for the criteria we use to make that call.

JOHOB Hardware Trading supplies this controller nationwide, covering NCR, Luzon, Visayas, Mindanao, and PEZA, SBMA, and Clark-registered facilities. Equipment sourced through JOHOB is built by an ISO 9001 certified partner factory, and electrical panels in this category carry CE marking. Where a project's water storage or booster package includes tanks, those are supplied under our TankSmith sister brand with WRAS-certified panel components where specified. After-sales support includes local warranty coverage and a dedicated point of contact for spares, replacement contactors, overload relays, or panel repair, so a fault in the field does not mean waiting on an overseas supplier. Because this controller is typically ordered alongside the pumps it controls, our team can quote the controller, the pump, and any accessories such as pressure switches or flow sensors as one line-itemed package with one delivery schedule, which keeps installation coordination on the buyer's side simpler than managing separate purchase orders and separate lead times from separate vendors. For buyers who need help specifying breaker size, enclosure rating, or lead-lag logic before requesting a quote, our sales team responds to RFQs within 1 business day with clarifying questions or a firm quotation, whichever the information provided supports.
