Simplex/Duplex Alternating Full Voltage Pump Controller, 2.0 HP 220V Philippines

A combination simplex/duplex alternating full voltage pump controller is a panel that starts and stops one or two pumps directly across the line, without a variable frequency drive. In simplex mode it runs a single pump. In duplex mode it runs two pumps and alternates which pump leads on each start cycle, which spreads wear evenly and keeps a backup pump ready if the lead unit needs service. Full voltage, also called across the line, starting applies motor voltage immediately at start, which is simpler and less expensive than a VFD panel for applications that run at a fixed duty point rather than needing variable speed. JOHOB Hardware Trading supplies this controller rated for 2.0 HP, 220V, 1-phase, 60Hz motors, matching the standard single-phase pump sizing used in Philippine commercial and light industrial buildings. It sits within JOHOB's broader Pumping and Pressure Systems category, alongside booster, transfer, and submersible pump packages and VFD duplex panels for sites that do need speed modulation. Buyers choosing between this controller and a VFD duplex panel should base the decision on whether the application needs pressure or flow modulation. If it runs at one fixed duty point, full voltage alternating control is the simpler and lower-cost option.

This controller is built around a 2.0 HP motor rated for 220V, single-phase, 60Hz supply, the standard voltage and frequency configuration for Philippine commercial buildings. The panel provides alternating duty control for two pumps (duplex) or standalone control for one pump (simplex), switching the lead pump automatically on each start cycle rather than running one pump continuously. Starting is full voltage (across the line), meaning the motor receives full line voltage at start rather than a ramped voltage or frequency profile from a VFD. Electrical panels in JOHOB Hardware Trading's catalog, including this one, carry CE marking. The panel is suited to a single, fixed duty point: if the installation calls for 2.0 HP, 220V, 1-phase, 60Hz pumps running at one consistent flow and pressure target with lead-lag redundancy, this specification matches that requirement directly. Buyers with a different voltage, phase, frequency, or horsepower requirement should request a quote with their exact specification, since JOHOB Hardware Trading configures panels to the site rather than offering only this single rating.

This controller fits Philippine commercial and institutional buildings that need simple duplex pump redundancy at a fixed 2.0 HP, 220V, 1-phase, 60Hz duty point: domestic water booster sets, sump and sewage ejector duplex systems, and smaller transfer pump applications where plumbing code requirements call for a backup pump rather than variable speed control. JOHOB Hardware Trading supplies equipment nationwide, covering NCR, Luzon, Visayas, Mindanao, and PEZA, SBMA, and Clark economic zones, so the same controller specification is available whether the installation is in Metro Manila or a provincial site. Because the panel uses full voltage starting rather than a VFD, it suits buildings where the pump load does not vary enough to justify the added cost of speed control, such as fixed-demand sump pits or booster sets serving a stable occupancy load. For buildings with variable demand, such as high-rise domestic water booster systems that need pressure modulation across occupancy swings, JOHOB Hardware Trading's VFD duplex panels are the better fit within the same Pumping and Pressure Systems category.

JOHOB Hardware Trading prices this controller on a quote basis and does not publish a fixed price, since final cost depends on panel configuration, enclosure requirements, and site-specific accessories. RFQs receive a response within 1 business day. Standard lead time is 21 to 35 days for ex-stock configurations or 45 to 90 days for made-to-order panels, so buyers should factor lead time into installation scheduling before committing to a project timeline. 12% VAT applies for VAT-registered buyers purchasing nationwide. PEZA and SBMA locators and exporters qualify for zero-VAT treatment on eligible purchases, which should be confirmed at quote stage with the relevant documentation. Buyers planning budget approval or procurement timelines should request a formal quote referencing the 2.0 HP, 220V, 1-phase, 60Hz specification directly, since pricing is not estimated from a published list and will vary by configuration.

Full voltage alternating control and VFD duplex control solve the same lead-lag redundancy problem differently. A full voltage alternating panel, like this 2.0 HP, 220V, 1-phase, 60Hz controller, starts each pump directly across the line and alternates which pump leads, with no speed adjustment. It is the simpler and lower-cost panel for a fixed duty point. A VFD duplex panel, also in JOHOB Hardware Trading's Pumping and Pressure Systems catalog, ramps pump speed up and down through a variable frequency drive, which adds soft-start capability and lets the system modulate pressure or flow as demand changes. The tradeoff is cost and complexity against flexibility: full voltage alternating control costs less and has fewer components to maintain, while a VFD duplex panel costs more but handles variable demand and reduces mechanical stress from repeated full-voltage starts. Buyers should specify which demand profile they have, fixed or variable, when requesting a quote so JOHOB Hardware Trading can confirm whether a full voltage alternating controller or a VFD duplex panel is the better match.

JOHOB Hardware Trading supplies this controller nationwide across NCR, Luzon, Visayas, Mindanao, and PEZA, SBMA, and Clark economic zones, with local warranty and after-sales support included regardless of site location. Electrical panels in this catalog, including this controller, carry CE marking, and the manufacturing partner operates under ISO 9001 quality management with TUV SUD testing on supplied equipment. These certifications cover the panel hardware itself. Buyers with a site-specific requirement for a different certification, such as UL or FM listing, should raise that at RFQ stage since it is not a standard inclusion. RFQs receive a response within 1 business day, and after-sales support covers the panel through its local warranty period. For provincial and economic-zone buyers, the same specification, lead time, and VAT treatment described above apply regardless of distance from Metro Manila.
