Duplex VFD Jockey Pump Controller for Philippine Fire Protection Systems

A jockey pump controller keeps a fire protection system pressurized between cycles of the main fire pump, topping up small pressure losses from valve seepage or minor leaks so the main pump does not start for every drop. A duplex configuration runs two jockey pumps instead of one, alternating which unit carries lead duty and which sits on standby, so a single pump failure does not leave the system without pressure support. Adding a VFD (variable frequency drive) to that duplex setup lets each pump ramp speed up and down to hold the pressure setpoint, instead of switching on and off at fixed speed. That reduces the start and stop cycling that wears out contactors and pump bearings over time, and it holds pressure inside a tighter band, which matters for buildings running NSPC/NBC compliant fire protection. JOHOB supplies duplex VFD jockey pump controllers built around Inovance and Chutian drives, the same electrical panel line used across our VFD, SDE, star-delta, and MCC panel category, sized to the building's setpoint and pipe volume rather than sold off a generic catalogue spec sheet. The panel and drives carry CE marking and are sourced through an ISO 9001 certified partner factory, with TUV SUD testing behind the components, so the documentation is in place before the panel ships to site.

Every duplex VFD jockey pump panel JOHOB quotes is built to the specific project, not pulled off a shelf. The order includes the enclosure (indoor or IP55 outdoor rated to match the pump room), two variable frequency drives sized to the jockey pump motor's kW rating, and lead/lag alternation logic so duty rotates between the two pumps on every start cycle. Because the panel sits inside a fire protection system, JOHOB documents the certifications behind every component at handover: CE marking on the electrical assembly, ISO 9001 on the manufacturing partner's quality system, and TUV SUD test reports where applicable to the drives and switchgear. Pricing is quote based, JOHOB does not publish panel prices, because the drive rating, enclosure spec, and alternation logic all change the bill of materials from one project to the next. VAT-registered buyers see 12% VAT on the quote, PEZA and SBMA locators and exporters can be quoted zero-VAT where that status applies. Standard lead time is 21 to 35 days for ex-stock configurations, and 45 to 90 days when the panel is made to order against a specific drive or enclosure spec. JOHOB responds to RFQs within 1 business day, and payment terms are confirmed during that quote conversation rather than posted publicly.

A duplex VFD jockey pump controller is only sized correctly when it is sized against the main fire pump it supports, not in isolation. JOHOB works from the system's pressure setpoint, the volume of pipe the jockey pump has to hold pressurized, and the main fire pump's rated flow and pressure, so the jockey duty neither starts too often, a sign it is undersized against the leak rate, nor runs continuously against a VFD floor speed that never lets it rest, a sign it is oversized. This sizing exercise sits inside the same NSPC/NBC-aligned buying process JOHOB uses across its fire protection line, including diesel and electric fire pump packages and hydrant pump packages, so the jockey controller is quoted as part of a system, not a standalone accessory bolted onto whatever fire pump a building already has. Because sizing depends on setpoint and pipe volume that vary by building, JOHOB does not publish a generic hp table for duplex VFD jockey controllers. The RFQ process is where the drive rating gets confirmed against the project's actual fire protection design, using the setpoint, pipe volume, and main pump nameplate figures the buyer submits.

The duplex VFD jockey pump panel ships with the same certification set JOHOB documents across its electrical panel line. The panel assembly carries CE marking, confirming it meets the applicable electrical safety and EMC requirements for the drives and switchgear inside it. The manufacturing partner behind the panel operates under ISO 9001, so the panel is built under a documented quality management system rather than an ad hoc shop process. Components inside the panel, including the VFDs, are TUV SUD tested. Where the panel forms part of a pressure vessel assembly, such as when it is quoted alongside a pressure tank, ASME documentation applies to the vessel itself. JOHOB provides these certificates at handover as part of the standard delivery, not as a paid add-on, so the building's fire protection documentation package is complete when the panel arrives on site. This documentation set matters most for institutional buyers, hospitals, hotels, and PEZA or SBMA zone facilities, where fire protection equipment is checked against submitted specs before occupancy permits are released.

A simplex jockey pump controller runs a single pump with no built-in redundancy, if that pump or its controller fails, the fire protection system loses jockey duty entirely until it is repaired. A duplex configuration runs two pumps under one controller, alternating lead and standby duty so wear is shared evenly and a single pump or drive fault does not remove jockey support from the system. JOHOB's simplex and duplex full-voltage pump controller line covers smaller installations down to 2HP at 220V for buildings where a single jockey pump is adequate, while the duplex VFD configuration on this page targets installations where redundancy and tighter pressure-band control both matter, typically larger commercial, institutional, or PEZA/SBMA zone buildings with stricter fire protection uptime requirements. The choice between simplex and duplex, and between fixed-speed and VFD control, comes down to the building's occupancy classification and the fire protection engineer's design intent. JOHOB quotes either configuration and walks through the tradeoff during the RFQ conversation rather than defaulting every project to the highest spec panel available.

JOHOB does not publish prices for duplex VFD jockey pump controllers because the drive rating, enclosure spec, and alternation logic change the bill of materials project to project. What is fixed is the process: submit the fire protection system's pressure setpoint, pipe volume, and main fire pump rating through an RFQ, and JOHOB responds within 1 business day with a quote scoped to that spec. Standard lead time is 21 to 35 days for panels built from ex-stock drive and enclosure combinations, extending to 45 to 90 days for made-to-order configurations. VAT-registered buyers are quoted with 12% VAT included, while PEZA and SBMA locators and exporters can be quoted zero-VAT where that status applies, a distinction worth flagging in the RFQ since it changes the landed cost materially. JOHOB does not post milestone billing schedules for this equipment class publicly, payment terms are confirmed during the quote conversation itself, alongside the certification package (CE, ISO 9001, TUV SUD) that ships with the panel.

JOHOB delivers duplex VFD jockey pump controllers nationwide, covering Metro Manila, the rest of Luzon, Visayas, and Mindanao. This includes projects inside PEZA, SBMA, and Clark economic zones, where the zero-VAT treatment for qualified locators and exporters applies to the panel quote. Because sizing depends on the building's fire protection design rather than a fixed catalogue, JOHOB handles delivery the same way whether the project is a hotel in Metro Manila, a hospital in Visayas, or a factory inside a Clark zone facility, the RFQ intake captures the setpoint, pipe volume, and main pump rating regardless of location, and the quote comes back with the applicable lead time and VAT treatment already factored in. Buyers outside NCR should flag the delivery address and zone status in the initial RFQ so the freight and VAT treatment are quoted correctly the first time, avoiding a revised quote later in the process.
