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

A bladder tank is a type of hydropneumatic pressure tank built around a flexible internal bladder, usually rubber or butyl, that physically separates the water chamber from a pre-charged air chamber. As a booster or transfer pump pushes water into the tank, the bladder expands and compresses the air above it, storing pressure. When a fixture downstream opens, that stored pressure pushes water back out before the pump needs to cycle on again. This design keeps the air permanently isolated from the water, unlike older bladder-less tanks where the two mix and the air charge has to be topped up manually over time. For commercial and industrial buyers in the Philippines, the practical effect is fewer pump starts per hour, less wear on motors and contactors, and smoother pressure at the tap or outlet. Bladder tanks are a standard component in booster sets, fire pump jockey circuits, and transfer systems feeding elevated storage, and they come in a range of capacities to match a building's peak demand and pump duty cycle. Sizing depends on system flow rate, pump cut-in and cut-out pressure, and acceptable cycling frequency, which is why tank selection should be confirmed against the specific pump curve rather than picked by tank size alone.

JOHOB supplies Varem-equivalent bladder pressure tanks sourced from a vetted overseas partner factory, not manufactured in-house. The partner factory operates under an ISO 9001 quality management system, and the tanks are TUV SUD tested, with CE marking on the electrical components of any paired pump or panel set and ASME-rated construction where the application calls for it. This sourcing model, rather than owning the factory, is the same approach JOHOB uses across its pumping and pressure systems catalog, and it is also why JOHOB describes these as Varem-equivalent tanks rather than claiming authorized-dealer status for the Varem brand specifically, since that is not a certification JOHOB holds. What buyers get instead is a documented chain: certified manufacturing standards, test reports available on request, and local after-sales support instead of a direct import arrangement with no local point of contact. For procurement teams running a vendor qualification process, this means the certifications travel with the equipment and can be verified independently of the brand name on the tank. JOHOB's role is to qualify the factory, manage the import and compliance paperwork, and stand behind the equipment locally with warranty and spare parts support, which matters more for lifecycle cost than the nameplate alone.

Pricing for bladder pressure tanks is quote-based since capacity, pressure rating, and connection size vary by project, and JOHOB does not publish list prices. What is fixed is the response time: every request for quote gets an answer within 1 business day. Lead times depend on whether the tank is an ex-stock size or a made-to-order configuration. Ex-stock sizes typically ship in 21 to 35 days, while made-to-order tanks, larger capacities, or non-standard pressure ratings run 45 to 90 days. Standard VAT-registered buyers are charged the standard 12% VAT. Buyers operating under PEZA or SBMA locator status, and exporters, qualify for zero-VAT treatment on the purchase, which should be flagged at quote request so the paperwork is prepared correctly from the start. Delivery covers the full country: NCR, the rest of Luzon, Visayas, and Mindanao, including direct delivery into PEZA, SBMA, and Clark economic zones. Buyers planning a project timeline should request a quote as early as the design stage if the tank size falls outside common ex-stock capacities, since the 45 to 90 day made-to-order window can become the critical path on a tight construction schedule.

Not every bladder tank problem means buying a new tank. If an existing pressure tank is losing its air charge quickly, cycling the pump too often, or showing signs of a waterlogged tank, the issue is often a worn or ruptured bladder inside a shell that is otherwise still serviceable. That is a replacement-bladder job, not a new-tank purchase, and it is a separate service from what this page covers. This page is for buyers who need a complete new bladder tank, whether for a new installation, a capacity upgrade, or a tank that has failed structurally rather than just at the bladder. If the existing shell is sound and only the bladder has failed, see JOHOB's dedicated page on Varem bladder replacement for pricing and turnaround specific to that service instead of a full tank order. Getting this distinction right before requesting a quote saves a procurement cycle, since replacement parts and full tank assemblies are priced, sourced, and lead-timed differently.

A bladder tank rarely stands alone. It is typically paired with a booster, transfer, or submersible pump set, and often a VFD duplex control panel that modulates pump speed to match demand and reduce cycling further. In fire protection applications, a smaller bladder or jockey tank maintains line pressure between pump starts in a sprinkler or fire reserve system. JOHOB supplies all of these as part of the same pumping and pressure systems catalog, along with the electrical panels (VFD, SDE, star-delta, MCC), piping, fittings, and valves needed to complete the installation, so a bladder tank order can be scoped alongside the rest of the system rather than sourced separately from a different supplier. This matters for commissioning: a bladder tank sized without reference to the actual pump curve and control logic will cycle incorrectly regardless of its own build quality. Buyers scoping a new booster set or retrofitting an existing one should request the bladder tank and the pump and panel package together so sizing is checked as one system rather than three separate purchases that may not agree with each other once installed.
