500 Liter Pressure Tank Price in the Philippines: What Drives Your Quote

Most buyers searching for a 500 liter pressure tank price in the Philippines are budgeting a booster set, not buying a vessel in isolation. We quote rather than publish, because the figure moves with membrane type (bladder or diaphragm), maximum working pressure, flange or threaded connection size, factory of origin, and whether the tank ships alone or as part of a pump and panel package.

For market context, publicly listed retail prices from Philippine online hardware sellers (checked August 2026) put 200 to 300 litre butyl bladder vertical tanks in the PHP 17,500 to PHP 21,500 band, while larger bladder tank ranges from the same sellers extend past PHP 300,000 as capacity and working pressure climb. A 500 litre unit sits above that 200 to 300 litre band, and the spread at that size is wide enough that a single published number would mislead more buyers than it would help. What we commit to instead is a written quotation with the line items broken out (tank, pump, control panel, fittings, freight, VAT) so procurement can compare like with like across bidders. Send the specification points listed further down this page and we respond within 1 business day. Pricing is quote-based across our full range and we do not disclose prices publicly, for the same reason a mechanical contractor does not publish a lump sum for a pump room: the correct number depends on the system the equipment serves, not on the capacity printed on the nameplate.

A pressure tank does not store usable water in any meaningful volume. It stores compressed air behind a membrane, and that air is what absorbs the difference between what the pump delivers and what the building draws. The number that matters is not the 500 litre nameplate volume, it is the drawdown: the litres you get out between cut-in and cut-out pressure. Drawdown is always a fraction of nominal volume, and that fraction falls as your working pressure differential narrows. This is why a 500 litre tank on a system running a wide pressure band can outperform a larger tank on a narrow band. Size the tank against pump cycling, not against tank volume. The standard method is to take the pump flow rate, decide the maximum acceptable starts per hour for that motor, and solve for the drawdown that keeps the pump running long enough per cycle to avoid short cycling; our pressure tank sizing calculator runs that arithmetic in your browser. Short cycling is what destroys motors, contactors, and check valves, and it is the single most common reason a building ends up replacing a booster set years early. Where the system runs a VFD, the tank sizing logic changes again, because the drive holds pressure across a range instead of bouncing between two setpoints, and the tank is there mainly to handle small draws and to stop the drive from hunting; the comparison is in VFD versus fixed speed pumps. Tell us which of those two cases you are in and the sizing conversation gets much shorter.

Six data points let us return a firm quotation instead of a range. First, membrane type: a replaceable bladder or a fixed diaphragm. Bladder units keep the water entirely inside the membrane so it never touches the shell, which suits potable systems and makes field replacement possible without swapping the vessel. Diaphragm units are simpler and generally cost less at the same capacity; the same decision at the smaller size is covered on our page for the 200L diaphragm pressure tank supplier in the Philippines. Second, maximum working pressure in bar or psi, taken from the highest pressure the pump can generate at shut-off, not from the operating setpoint. Third, pre-charge pressure, which should be set relative to your cut-in pressure and checked with the tank isolated and drained. Fourth, connection type and size: threaded or flanged, and the nominal diameter matching your header. Fifth, orientation and footprint, because a 500 litre vertical unit needs headroom for membrane service and a horizontal unit needs floor area you may not have in a pump room. Sixth, the fluid and temperature, since potable cold water, chilled water, and hot water service each call for different membrane material. If you also tell us the pump make and model already on site, or that the tank is going into a new package, we can check the pairing before quoting instead of after. Missing data is what turns a one day turnaround into a week of back and forth, so send what you have and we will flag what is still needed.

Procurement and QA usually need three things on file before a purchase order clears, and all three should be settled at quotation stage rather than at delivery. On certification, the equipment we supply carries ISO 9001 manufacturer quality management system coverage, TUV SUD testing, CE marking on electrical items, and ASME on pressure vessels where applicable. Where a project also involves stored potable water, the modular tank panels we supply are WRAS certified. We will state on the quotation exactly which certificates apply to the specific items quoted, and we send the documents rather than describing them. On tax, 12% VAT applies to VAT-registered buyers. Zero-VAT applies to PEZA and SBMA locators and to exporters, and if you fall in that category tell us at RFQ stage so the quotation is issued correctly from the start instead of being reissued later. On schedule, standard lead times are 21 to 35 days ex-stock and 45 to 90 days made-to-order. Which band applies depends on membrane type, working pressure rating, and connection configuration, since non-standard pressure ratings and flange sizes move an order from stock into production. We state the applicable band on every quotation. RFQs receive a response within 1 business day, and where a date is genuinely at risk we say so before the purchase order rather than after.

A pressure tank quoted on its own is usually the wrong purchase. In practice the 500 litre unit is one component in a booster package, and quoting the package together is what keeps the pressure band, the pump curve, and the control logic consistent. On the pump side we supply established brands including Grundfos, DAB, and Speroni through our range of commercial booster pumps, along with CDL Chinese engineered vertical multistage pumps where the budget calls for it and the duty point allows. On the control side we supply VFD duplex control panels, star-delta and SDE starters, and motor control centres, built by Chutian using Inovance drives. A duplex VFD arrangement matters here because it alternates lead and lag pumps, holds a setpoint across varying demand, and materially changes how much drawdown the tank actually needs to provide. We also supply the connecting hardware in the same scope: stainless steel flexible hoses to take up pump vibration and misalignment at the tank and header connections, plus ball and gate valves for isolation so the tank can be serviced without draining the riser. Where a project needs storage upstream of the booster, FRP modular water tanks for upstream storage in FRP, GRP, hot dip galvanised, and stainless steel are supplied through our sister brand TankSmith, which handles the turnkey installation side. Quoting the whole pump room as one scope removes the interface risk that shows up when three suppliers each deliver a correct component that does not match the others.

We deliver nationwide: NCR, the rest of Luzon, Visayas, and Mindanao, including PEZA zones, SBMA, and Clark. Freight is a quoted line item rather than a hidden cost inside the unit price, so you can see what you are paying to get equipment to site and can elect to arrange your own hauling if that works out better for your project. The reason we source from both Philippine and China factories is that it gives us two supply routes for the same specification, which matters when one route is on a long production queue and your commissioning date is fixed. Equipment is supplied with local warranty and after-sales support handled here in the Philippines, not routed back to a foreign factory support desk on a different time zone, which is the practical difference between a membrane replacement taking days and taking months. For commercial, industrial, and institutional buyers this is usually the deciding factor over a marginally cheaper unit bought direct, since the cost of a pump room being down is measured in operations, not in equipment. If you are specifying rather than buying, send the drawings and we will comment on the tank sizing before you issue the tender documents; the pump-side arithmetic is in how to size a booster pump for a commercial building, and the full capacity ladder sits on the hydropneumatic bladder pressure tank capacity range page. If you are already at purchase order stage, send the specification points listed above and expect a response within 1 business day.
