15 HP VFD Duplex Booster Pump System Supplier in the Philippines

A 15 HP VFD duplex booster pump system pairs two pumps of matched horsepower with a single variable frequency drive control panel. The VFD panel alternates duty and standby operation between the two pumps, so wear is shared evenly and the system keeps working if one pump needs servicing. A pressure transducer feeds the panel real-time line pressure, and the VFD adjusts motor speed continuously to hold a constant pressure setpoint rather than cycling the pump on and off at fixed speed. JOHOB Hardware Trading builds these control panels under its Electrical Panels product line, which covers VFD, SDE, star-delta, and MCC panel types using Inovance and Chutian drive components. The panel enclosure, wiring, and drive hardware are supplied by an ISO 9001 certified partner factory, and the electrical assembly carries CE marking. Because the panel is duplex rather than simplex, it is sized for buildings where continuous water pressure cannot depend on a single pump, such as multi-story structures with overlapping peak-demand periods across floors. The complete system package typically includes the two pumps, the VFD duplex control panel, the pressure sensor, and the interconnecting piping and valve accessories needed to commission the set as one working unit, rather than requiring the buyer to source and match components separately.

A 15 HP duplex VFD booster system sits in the mid-to-upper range of JOHOB's booster pump lineup, sized for buildings where a single smaller pump cannot maintain pressure across all fixtures during peak draw. JOHOB supplies these systems to commercial, industrial, and institutional buyers nationwide across the Philippines, covering NCR, the rest of Luzon, Visayas, and Mindanao. Buyers operating inside PEZA, SBMA, or Clark zones can source the same system under zero-VAT terms if they qualify as locators or exporters. Typical building types that specify a duplex VFD system at this horsepower include hotels, hospitals, and other multi-tenant or multi-floor commercial buildings where water demand varies through the day and downtime on a single pump is not acceptable. Because the panel runs duty/standby alternation rather than a single working pump, the building keeps pressurized water supply even while one pump is pulled for maintenance. Buyers still confirming whether 15 HP is the right size for their building, rather than a smaller or larger duplex or triplex configuration, can work from JOHOB's VFD sizing guide and duplex-vs-triplex guide before submitting an RFQ, so the quote that comes back already matches the building's real peak demand instead of a generic default.

The electrical components in a 15 HP VFD duplex booster panel carry CE marking, consistent with JOHOB's standard for electrical and material handling equipment. The panel is built by an ISO 9001 certified partner factory, meaning the factory's quality management system is certified to the ISO 9001 standard, and components are TUV SUD tested before the panel ships. Where the complete system package includes a hydropneumatic pressure tank alongside the duplex pump set, that tank component falls under JOHOB's ASME certification for pressure vessels where applicable. JOHOB does not manufacture the panel or pumps in-house; equipment is sourced from a vetted overseas manufacturer and a partner factory, then supplied with local warranty and after-sales support from JOHOB directly. This matters for procurement teams that need to document certification chains for compliance or insurance purposes: the certifications above (ISO 9001, CE marking, TUV SUD, ASME where applicable) are attached to the equipment itself, not to JOHOB as a reseller, and can be requested as part of the RFQ documentation package.

JOHOB prices duplex VFD booster pump systems on a quote basis; no public price list is published for this configuration, because final cost depends on pump brand and stage count, panel enclosure spec, and whether a pressure tank is bundled into the package. Buyers submitting an RFQ receive a response within 1 business day. For VAT-registered buyers, standard 12% VAT applies to the quoted price. Buyers operating as PEZA or SBMA locators, or as registered exporters, qualify for zero-VAT invoicing on the same equipment. Lead time depends on whether the specific pump and panel configuration is held ex-stock or needs to be built to order: ex-stock configurations ship in 21 to 35 days, while made-to-order configurations, which is common for a specific 15 HP duplex spec, run 45 to 90 days. Buyers on a tight installation schedule should confirm ex-stock availability for their exact horsepower and voltage requirement at RFQ stage, since a made-to-order lead time needs to be built into the project's construction timeline rather than assumed away.

A duplex VFD booster pump rarely operates alone. Most commercial buildings pair the booster set with a water storage tank sized to the building's daily demand and fire reserve requirement. JOHOB's sister brand, TankSmith, supplies FRP, GRP, HDG, and stainless steel modular water tanks and handles turnkey installs, so a buyer sourcing a 15 HP duplex VFD booster system through JOHOB can also request the storage tank as part of the same RFQ instead of running two separate vendor conversations. This is relevant for buildings starting from a blank water system design, where the tank, the booster panel, and the pressure vessel need to be sized together rather than sequentially. Buyers who already have an existing tank and only need the booster pump and VFD panel replaced or added can request the pump system on its own; the two product lines are supplied together or separately depending on what the project needs.
