JOHOB Hardware Trading supplies Varem-equivalent bladder pressure tanks, hydropneumatic vessels that use a rubber bladder to separate air from water in booster and building water systems, nationwide across NCR, Luzon, Visayas, Mindanao, and PEZA, SBMA, and Clark locators. Tanks are sourced through an ISO 9001 certified, TUV SUD tested partner factory, ASME-rated where applicable, at quote-based pricing with 21 to 35 day ex-stock lead times and RFQ replies within 1 business day.

What a Varem Bladder Tank Is and How It Works

A Varem bladder tank is a hydropneumatic pressure vessel used in booster and building water systems. Inside the tank, a flexible rubber bladder separates a pressurized air charge from the water supply. As a booster pump runs, water enters the tank and compresses the air behind the bladder; when a tap or fixture draws water, the compressed air pushes water back out through the system. This buffer lets the pump satisfy small draws without switching on and off for every faucet, toilet flush, or shower, which reduces pump cycling, lowers motor wear, and keeps line pressure more consistent across a building.

Bladder-style tanks are the standard choice for commercial and institutional booster systems, condominiums, hotels, hospitals, and light industrial buildings where steady pressure matters and frequent pump starts shorten motor life. They pair directly with duplex or triplex booster pump sets and VFD control panels, which regulate pump speed to match demand. Sizing a bladder tank correctly, matching its drawdown volume and pre-charge pressure to the building's peak demand and pump cut-in/cut-out settings, is what determines whether the system actually reduces cycling or just shifts the problem. JOHOB sizes bladder tanks against the pump curve and building demand profile submitted with each RFQ, rather than selling a single fixed size for every project.

JOHOB's Sourcing and Certifications for Varem-Equivalent Tanks

JOHOB Hardware Trading supplies Varem-equivalent bladder pressure tanks, not Varem-branded units. Components are sourced through an ISO 9001 certified partner factory and are TUV SUD tested, with ASME rating applied where the pressure vessel class requires it. This sourcing model lets JOHOB offer bladder tank specifications and build quality comparable to name-brand European bladder tanks, backed by an internationally recognized quality management certification and third-party testing, without the extended lead times and import costs of ordering a specific European brand direct.

Buyers evaluating a bladder tank supplier for a PH-based project should ask for the ISO 9001 certificate and TUV SUD test report as part of the RFQ process, not take certification claims on a website at face value. JOHOB provides this documentation on request as part of the standard quote package, alongside the tank's rated working pressure, drawdown volume, and connection sizing, so the specifying engineer or procurement team can verify fit against the project's plumbing design before committing to an order.

Nationwide Availability and PEZA/SBMA Zero-VAT Terms

JOHOB delivers bladder pressure tanks nationwide across the Philippines, covering Metro Manila and the rest of Luzon, the Visayas, and Mindanao, as well as PEZA, SBMA, and Clark economic zones. Projects inside PEZA or SBMA, and export-oriented buyers, qualify for Zero-VAT treatment on the purchase; buyers outside those zones who are VAT-registered are invoiced with the standard 12% VAT. Confirming zone status and VAT classification at RFQ stage avoids invoicing corrections later in the order, particularly for locator companies that need Zero-VAT documentation for their own compliance filings.

Nationwide delivery means a hotel in Cebu, a hospital in Davao, or a factory inside a Luzon economic zone can all specify the same bladder tank sourcing and certification standard, rather than sourcing locally through a regional supplier with inconsistent documentation. For multi-site operators standardizing pump room equipment across several PH locations, working with one supplier for bladder tanks, booster pumps, and VFD panels also simplifies spare-parts stocking and warranty claims to a single point of contact.

Lead Times, Pricing, and How to Request a Quote

Bladder tank pricing at JOHOB is quote-based; the company does not publish per-unit prices, since final cost depends on tank capacity, rated pressure, connection configuration, and order volume. Standard lead time is 21 to 35 days for ex-stock configurations and 45 to 90 days for made-to-order specifications, and JOHOB responds to RFQs within 1 business day.

To get an accurate quote, submit the target booster pump's flow rate and head, the building's peak demand period, and the pump's cut-in and cut-out pressure settings alongside the RFQ. This lets JOHOB size the bladder tank's drawdown volume correctly instead of quoting a generic tank that undersizes or oversizes the buffer. For repeat or multi-site orders, note the PEZA/SBMA zone status and VAT registration status in the same RFQ so the quote reflects the correct VAT treatment from the first reply, rather than requiring a revised quote later in procurement.

Bladder Tank Supply vs. Bladder Replacement Service

JOHOB addresses two separate Varem-equivalent bladder tank needs, because they answer different questions. This page covers new bladder tank supply: sourcing a complete pressure tank for a new booster system or an expansion. Replacing a worn or ruptured bladder inside a tank you already own is a separate, lower-cost repair than replacing the whole tank.

If your existing pressure tank is losing air charge, cycling the pump more frequently than it used to, or showing a wet bladder pinhole, that is a replacement job, not a new-tank purchase. If you are speccing a booster system for a new building, an expansion, or a system upgrade with a larger duplex or triplex pump set, that is a new-tank supply job covered on this page. RFQs for either case get the same 1 business day response time and go through the same ISO 9001 certified, TUV SUD tested sourcing.

Where Bladder Tanks Fit in a Complete Pump and Pressure System

A bladder tank rarely sits on its own; it is one component of a complete pumping and pressure system. JOHOB supplies the full stack for booster and transfer applications: duplex and triplex booster pumps, VFD control panels (including Inovance and Chutian drives) that vary pump speed to match demand instead of running pumps at fixed speed, and the SS flexible hose, ball valves, and gate valves used in the pump room piping.

Specifying the pump, VFD panel, and bladder tank together, rather than sourcing each from a different supplier, keeps the pressure settings, drawdown volume, and pump curve consistent across the system, which is where most booster system problems (short-cycling, pressure swings, premature motor failure) actually originate. Buyers scoping a full booster room upgrade can request a combined RFQ covering pumps, panel, tank, and piping accessories, with the same 21 to 35 day ex-stock or 45 to 90 day made-to-order lead time and 1 business day RFQ response that applies to bladder tanks alone.

Frequently Asked Questions

1

Is JOHOB an authorized Varem dealer in the Philippines?

No. JOHOB supplies Varem-equivalent bladder pressure tanks, not Varem-branded products, and does not claim authorized dealer or distributor status for the Varem brand. The tanks are sourced through an ISO 9001 certified, TUV SUD tested partner factory and are built to comparable specifications: rubber bladder separation, rated working pressure, and drawdown volume matched to your booster pump. This lets JOHOB offer similar performance and documentation at PH-based lead times of 21 to 35 days ex-stock or 45 to 90 days made-to-order, without the import timeline of ordering the Varem brand directly.

2

What sizes of bladder pressure tanks does JOHOB supply?

JOHOB supplies bladder pressure tanks across a range of capacities, from smaller diaphragm-style units to larger-capacity tanks for building booster systems, sized against your pump's flow rate, head, and cut-in/cut-out settings rather than sold as one fixed size. Submit your booster pump specifications and peak demand period with your RFQ so the tank's drawdown volume is matched correctly. JOHOB also publishes size-specific reference pages, including a 200-liter diaphragm tank and a 500-liter pressure tank, for buyers who already know their target capacity.

3

What certifications back JOHOB's bladder tanks?

Bladder tanks sourced through JOHOB trace to an ISO 9001 certified partner factory and are TUV SUD tested. Where the pressure vessel class requires it, tanks carry an ASME rating. JOHOB provides the ISO 9001 certificate and TUV SUD test report as part of the standard RFQ and quote package on request, so procurement and specifying engineers can verify certification before placing an order rather than relying on website claims alone.

4

How much does a Varem-equivalent bladder tank cost and how fast can it ship?

Pricing is quote-based and depends on tank capacity, rated pressure, and connection configuration, so JOHOB does not publish a fixed price list. Standard lead time is 21 to 35 days for ex-stock configurations and 45 to 90 days for made-to-order specifications. RFQs get a response within 1 business day. Buyers inside PEZA or SBMA, and export-oriented companies, qualify for Zero-VAT treatment; other VAT-registered buyers are invoiced with the standard 12% VAT.

5

Does JOHOB replace a worn bladder in an existing pressure tank, or only sell new tanks?

Both. New bladder tank supply is covered on this page. Replacing a worn or ruptured bladder inside a tank you already own is a separate, lower-cost service. If your existing tank is losing air charge or your pump is short-cycling more than it used to, that usually points to a replacement job rather than a full tank purchase; JOHOB can help determine which applies based on the symptoms you describe in the RFQ.

6

Which parts of the Philippines does JOHOB deliver bladder tanks to?

JOHOB delivers nationwide, covering Metro Manila and the rest of Luzon, the Visayas, and Mindanao, plus PEZA, SBMA, and Clark economic zones. Zone status affects VAT treatment: PEZA/SBMA locators and export-oriented buyers qualify for Zero-VAT, while other VAT-registered buyers outside those zones are invoiced with the standard 12% VAT. Confirm your zone and VAT registration status when submitting an RFQ so the quote reflects the correct tax treatment from the first reply.
