Variable Speed Booster Pump System Quotation for Metro Manila Buildings

A variable speed booster pump system quotation from JOHOB is a line-item document, not a single lump sum figure. Every line carries a make, a model reference, and a quantity, so your project engineer or procurement officer can check the document against the approved plumbing plan before releasing it for approval.

The document lists the pump set (a vertical multistage centrifugal pump arrangement in simplex, duplex, or triplex configuration), the VFD duplex pump control panel, the hydropneumatic pressure tank, the suction and discharge manifold, stainless steel flexible hose connectors, isolation ball or gate valves, and the pressure transducer and gauge set. We quote against a duty point rather than a building type, so the document states the design flow in liters per second (or gallons per minute, if your plans use imperial units) and the total dynamic head in meters, together with the static lift and friction allowance we assumed. Where the specification names an established brand, we quote Grundfos, DAB, or Speroni. Where the budget favors an engineered Chinese vertical multistage unit, we quote CDL. Control panels are quoted as Chutian panels built around Inovance variable frequency drives. The quotation also states the lead time band that applies to your configuration, the VAT treatment for your entity type, and the delivery point in Metro Manila. Pricing is quote-based and we do not publish price lists, because head, flow, material of construction, and panel specification move the number far more than the pump nameplate does.

The fastest quotations are the ones where the buyer sends complete data on the first message, so here is the full list. First, the building profile: number of floors served by the booster, the height in meters from the pump slab to the highest fixture, and the number of units or fixtures on the served risers. Second, the water source: whether the booster draws from a ground cistern, a roof tank, or a direct city line, and the usable capacity of that storage in liters. Third, the duty point if your consultant has already computed it, meaning design flow and total head. If it has not been computed, send the fixture unit schedule or the riser diagram and we will work from that instead, using the method in our guide on how to size a booster pump for a commercial building. Fourth, the electrical supply at the pump room: voltage, phase, and frequency, plus the available breaker rating, because a variable frequency drive panel has to be matched to what the panel board can actually deliver. Fifth, the pump room dimensions and the door or hatch clearance, since a triplex skid has to physically enter the room. Sixth, whether this is a new installation or a replacement of an existing set, and if it is a replacement, the nameplate data of the current pumps. Seventh, your entity type for VAT treatment. Photographs of the existing pump room and panel are useful and often faster than measurements.

A fixed speed booster runs its motor at full speed whenever pressure drops below the cut-in setting, then shuts off at cut-out, so the pressure your tenants feel swings between those two points and the motor absorbs a full start every cycle. A variable speed system holds a constant discharge pressure by modulating motor speed against a pressure transducer signal, so morning peak and 3am trickle demand both land at the same setpoint. In a Metro Manila condominium or hotel, that difference shows up in three places. Tap and shower pressure stops fluctuating when neighboring units draw at the same time. Motor starts drop sharply because the drive ramps rather than slams, which reduces mechanical stress on the pump, the coupling, and the mechanical seal. And a variable speed set can be built as a duplex or triplex arrangement where the drive stages additional pumps in only when the lead pump reaches its speed ceiling, with automatic alternation so run hours distribute evenly across the set instead of accumulating on one machine. The hydropneumatic pressure tank still matters on a variable speed system, but it is sized for small demand buffering rather than for absorbing every start. If you want the engineering comparison in full, including where a fixed speed set is still the correct and cheaper answer, read our guide on VFD versus fixed speed pumps before you finalize the specification.

JOHOB Hardware Trading sources from both Philippine and China factories, which means a single quotation can present more than one commercial option against the same duty point. On the pump side we supply Grundfos, DAB, and Speroni for specifications that call for established European brands, and CDL engineered vertical multistage pumps where the buyer wants comparable hydraulic performance at a different price point; the full range is on the page for the commercial booster pumps we supply in the Philippines. On the control side we supply Chutian panels built around Inovance variable frequency drives, configured for simplex, duplex, or triplex duty with automatic alternation. We also supply the surrounding scope from our own catalog rather than subcontracting it out: hydropneumatic pressure tanks, stainless steel flexible hoses, ball and gate valves, and the piping accessories that connect the set to your riser, or the whole thing as a complete booster pump system turn-key package. On certifications, the equipment we supply carries ISO 9001 manufacturer quality management system coverage, TUV SUD testing, and CE marking on electrical items where applicable. If your project also involves water storage, modular FRP, GRP, hot dip galvanized, and stainless steel tanks are supplied under our sister brand TankSmith, and those panels are WRAS certified. Everything we deliver comes with local warranty and after-sales support in the Philippines, which is the practical reason buyers choose a local supplier over direct import: when a drive faults in year two, the support conversation happens in Manila and not across a time zone.

Two lead time bands apply, and your quotation will state which one governs your configuration. Standard configurations assembled from stock components ship in 21 to 35 days. Made-to-order sets, meaning non-standard duty points, special materials of construction, or panel builds outside our standard configurations, run 45 to 90 days. We publish these bands rather than promising a single number because the honest answer depends on whether your specified pump and drive combination is already in stock. If your construction schedule has a fixed handover date, tell us the required delivery week at RFQ stage and we will tell you plainly which band you are in before you commit; where the bands land in a real construction programme is mapped in our pump system project timeline guide. On tax treatment, 12 percent VAT applies to VAT-registered buyers in the ordinary case. Locators inside PEZA, SBMA, and Clark, and registered exporters, are quoted at Zero-VAT, so state your registration status in the RFQ and we will apply the correct treatment on the document instead of issuing a revision later. Delivery coverage is nationwide across the Philippines: NCR, the rest of Luzon, Visayas, and Mindanao, including PEZA, SBMA, and Clark locations. For Metro Manila sites specifically, name the exact delivery address and the receiving constraints (loading dock, hatch size, permitted delivery hours in the building), because those details affect the freight and handling line on your quotation.

Send your requirement through the quote request form on this page, or email it directly. We respond to RFQs within one business day. That first response is either the quotation itself, when the data you sent is complete enough to size against, or a short and specific list of what is still missing, so you are never left waiting without knowing why. If your consultant has already issued a bill of quantities or a pump schedule, attach it as is and we will quote line for line against your document rather than substituting our own format, which makes bid comparison straightforward for your evaluation committee. If no specification exists yet, send the riser diagram or the fixture schedule and we will propose a duty point and a configuration for your engineer to review before pricing is finalized. For buyers comparing several suppliers, ask each one to state flow, total head, control configuration, panel brand, and lead time band on the face of the quotation. Quotes that omit the duty point cannot be compared meaningfully, because a lower price against a smaller pump is not a lower price. A variable speed booster pump system quotation that states its assumptions is the one your evaluation committee can actually defend. If you are replacing an existing set in an occupied condominium rather than specifying for new construction, our page on condominium booster pump replacement in Manila covers the survey and coordination sequence for tenanted buildings.
