Varem Bladder Tank Supplier in the Philippines: Specs and Lead Times

A Varem bladder tank is a pressure vessel with a replaceable rubber bladder that separates water from compressed air, protecting booster and transfer pumps from short-cycling. JOHOB Hardware Trading supplies Varem-equivalent bladder pressure tanks nationwide in the Philippines, sourced from an ISO 9001 certified, TUV SUD tested partner factory, with 21 to 35 day lead times ex-stock and a quote within 1 business day.

A Varem bladder tank is a hydropneumatic pressure vessel that uses a replaceable rubber bladder to physically separate stored water from a compressed air cushion inside a steel shell. As a booster or transfer pump runs, water enters the bladder and compresses the air trapped between the bladder and the tank wall. When a tap or fixture draws water, the compressed air pushes water back out of the bladder, which lets the pump rest between draws instead of starting and stopping every few seconds. This bladder separation is the main difference from an older-style plain hydropneumatic tank, where air and water mix directly and the air charge needs frequent manual recharging. Because the air never contacts the pump or the piping, a Varem-style bladder tank also reduces the corrosion and water-hammer risk that plain tanks are prone to over time. In a typical commercial or institutional building, the bladder tank sits downstream of the booster pump set and ahead of the distribution piping, sized so the pump does not short-cycle under normal fixture demand. JOHOB sizes bladder tanks as part of a complete pump and pressure system rather than selling the vessel in isolation, so the tank, pump, and control panel are matched to the building's actual draw pattern.

JOHOB supplies Varem-equivalent bladder pressure tanks sourced from an ISO 9001 certified partner factory, with units TUV SUD tested and, where the application calls for it, ASME-rated pressure vessel construction. Electrical components paired with the tank, such as VFD duplex control panels, carry CE marking. JOHOB does not manufacture the tanks in-house; all units are supplied through a vetted overseas manufacturer and backed by local warranty and after-sales support in the Philippines. This sourcing model is the same one JOHOB uses across its pumping and pressure systems category, which lets the company apply one quality standard across booster pumps, VFD panels, and bladder tanks supplied as a matched system rather than as separate purchases from separate vendors. For procurement teams that need to document vendor quality for an audit or a government facility bid, JOHOB can provide the certification documentation for the specific tank model and lot being quoted. Buyers evaluating a Varem bladder tank for a hospital, hotel, food facility, or industrial site should ask for this documentation at quotation stage, since certification scope (ISO 9001 manufacturing QMS versus TUV SUD product testing versus ASME vessel rating) varies by tank size and application and is not identical across every SKU in the range.

Not every inquiry about a Varem bladder tank is for a brand-new unit. A common second case is a bladder tank already installed in a building, where only the internal rubber bladder has failed or lost its air charge, while the steel shell, piping, and fittings are still serviceable. JOHOB handles both cases: full tank supply for new installations or capacity upgrades, and bladder replacement for tanks already in service. The signs that point toward a replacement rather than a full tank swap include a pump that short-cycles even though the tank looks physically intact, water at the air charging valve (a sign the bladder has ruptured), or a tank that no longer holds air pressure after recharging. A full tank replacement is the better call when the steel shell itself is corroded, dented, or past its practical service life, or when the building's water demand has grown past what the existing tank size can buffer. JOHOB quotes both paths the same way, through a request for quotation that specifies the existing tank's capacity, pressure rating, and connection size for replacement parts, or the building's peak draw and pump specs for a new tank, with a response within 1 business day either way.

JOHOB quotes Varem bladder tanks on a request basis; pricing is not published publicly because tank size, pressure rating, and connection configuration change the unit cost. Standard lead time is 21 to 35 days for ex-stock sizes and 45 to 90 days for made-to-order configurations such as non-standard capacities or special connection types. JOHOB responds to every RFQ within 1 business day with a formal quotation. Delivery covers NCR, Luzon, Visayas, and Mindanao, including PEZA, SBMA, and Clark locators. Standard sales to VAT-registered buyers carry the 12% VAT; PEZA and SBMA locators and qualified exporters can purchase at zero-VAT where their registration applies, which should be stated on the purchase order or RFQ so the quotation reflects the correct tax treatment from the start. Buyers outside Metro Manila sometimes assume nationwide suppliers only quote NCR-based projects quickly and treat provincial sites as an afterthought; JOHOB's lead times and RFQ response time are the same nationwide, since delivery is scheduled from the same ex-stock and made-to-order inventory regardless of project location. For budget planning purposes ahead of a formal RFQ, buyers should expect the quoted price to reflect tank capacity, working pressure, and any bladder or vessel certification requested, rather than a flat per-liter rate.

A Varem bladder tank is rarely the only component in a working pressure system. JOHOB supplies bladder tanks alongside booster and transfer pumps, VFD duplex control panels, and the piping, valves, and stainless flexible hose needed to connect them. Sizing the tank without reference to the pump curve and the control panel's cycling logic is a common error that leads to a tank that is either oversized or undersized, where the pump still short-cycles despite a bladder tank being installed. JOHOB's approach is to size the bladder tank as part of the full booster or transfer system package, using the building's peak demand, the pump's flow and head, and the control panel's start and stop pressures together, rather than selling a tank in isolation and leaving the sizing math to the buyer. This matters most for multi-story commercial buildings, hotels, hospitals, and food facilities, where pump cycling frequency directly affects both equipment life and water pressure consistency at upper floors. Buyers who already have a pump and panel installed and only need a replacement or additional bladder tank should still share the existing pump's flow and head specs at RFQ stage, so JOHOB can confirm the tank size is still correctly matched before quoting.

JOHOB's role in the Varem bladder tank category is as a Philippines-based industrial equipment supplier serving commercial, industrial, and institutional buyers nationwide, not as the tank manufacturer. The practical advantage of buying through JOHOB rather than importing directly is the combination of a 1 business day RFQ response, 21 to 35 day ex-stock lead times, local warranty, and after-sales support, all handled within the Philippines rather than across an international supply chain the buyer has to manage themselves. For PEZA, SBMA, and Clark-based buyers, JOHOB also handles the zero-VAT documentation for qualified locators and exporters as part of the standard quotation process. JOHOB supplies bladder tanks as part of its pumping and pressure systems category, alongside VFD duplex control panels, booster and transfer pumps, and complete pump systems, which means a buyer sourcing a bladder tank for a new installation can also source the matched pump and control panel from the same RFQ and the same after-sales contact. For an existing installation needing only a bladder replacement, JOHOB quotes that separately from a full tank replacement so the buyer is not paying for a new shell when only the internal bladder has failed.
