Rubber Bladder Replacement for Varem Pressure Tanks: Philippines Pricing Guide

JOHOB does not publish a public price list for bladder pressure tanks, including Varem-equivalent replacement units. Pricing is quote-based and depends on three variables: tank capacity in liters, connection size, and pressure rating, since these determine vessel wall thickness and the bladder specification needed. A second variable is availability: units held ex-stock ship on a 21 to 35 day lead time, while made-to-order configurations run 45 to 90 days depending on capacity and certification requirements. Submitting these details with your RFQ gets a firm number back within 1 business day, rather than a range that has to be revised later. Buyers replacing a failed tank on an active booster pump system should flag the urgency in the RFQ so the quote can note whether an ex-stock unit matches the required specification, since ex-stock availability is what determines whether the 21 to 35 day window or the longer made-to-order window applies. There is no shortcut around the quote step: connection size and pressure rating mismatches are the most common cause of a wrong-fit replacement, and a vendor quoting a price without those two figures is guessing rather than sizing to the actual system.

Replacement bladder pressure tanks supplied by JOHOB are sourced from an ISO 9001 certified partner factory, meaning the manufacturing process itself is audited to a documented quality management system rather than the finished product alone. Units are also TUV SUD tested, and pressure vessel construction follows ASME requirements where applicable to the vessel class and rating. These are the certifications that matter for a pressure-holding component: a bladder or diaphragm that fails under normal system pressure is a safety issue, not just a maintenance inconvenience, so the certification chain on a replacement unit should match or exceed what was specified on the original installation. Procurement and facilities teams sourcing a replacement for an existing Varem installation should request the certification documentation alongside the quote, since matching the pressure rating and connection size on paper before the unit ships is faster and cheaper than a field mismatch after delivery. JOHOB includes this documentation as standard with the RFQ response, not as a separate request.

No. JOHOB is not an authorized Varem distributor. What JOHOB supplies is a Varem-equivalent bladder pressure tank, sourced from an ISO 9001 certified partner factory and matched to the same capacity, connection size, and pressure rating range that a Varem-specified project would call for. This distinction matters for procurement documentation: a spec sheet or BOQ that names Varem specifically should be updated to reference an equivalent-spec bladder pressure tank if JOHOB is the intended supplier, so the paperwork matches what is actually being delivered. For buyers who need brand-matched replacement parts under an existing service agreement or warranty with the original Varem supplier, that conversation should go through the original supplier's channel. For buyers replacing a failed unit outside of a brand-specific service agreement, an equivalent-spec tank quoted against the same capacity, connection size, and pressure rating is the practical path, and it is the one JOHOB can quote within 1 business day.

Standard lead times are 21 to 35 days for units held ex-stock and 45 to 90 days for made-to-order configurations, with the specific window confirmed in the RFQ response based on the capacity and pressure rating requested. Delivery coverage is nationwide: NCR, Luzon, Visayas, and Mindanao, including PEZA, SBMA, and Clark economic zone sites. For a facility running on a single pressure tank with no redundant unit, the lead time is often the deciding factor between an ex-stock and made-to-order specification, since a failed bladder tank on a booster system can mean reduced or interrupted water pressure until the replacement is installed. Flagging the installation address and any zone registration (PEZA, SBMA, or standard VAT-registered) at RFQ stage lets the quote account for both the delivery logistics to that site and the correct VAT treatment in the same response, rather than requiring a second round of back-and-forth before a purchase order can be issued.

Standard VAT-registered buyers are quoted with 12% VAT applied. Buyers registered as PEZA or SBMA locators, or operating as exporters under the applicable zero-rating rules, are quoted at zero-VAT instead. This distinction should be confirmed at RFQ stage, since it changes the landed cost of the replacement tank and affects how the purchase order and invoice are structured for the buyer's own compliance and input VAT treatment. Facilities operating inside an economic zone frequently have existing zero-VAT purchase documentation on file for other equipment purchases; the same registration status applies to a bladder pressure tank replacement, so there is no separate approval process required beyond confirming the registration details JOHOB already asks for on the RFQ form. Buyers unsure of their own VAT status should raise it during the quote request rather than after the purchase order is issued, since correcting VAT treatment after invoicing is slower than confirming it upfront.

A fast, accurate quote depends on five pieces of information: tank capacity in liters, connection size, pressure rating, whether an ex-stock or made-to-order timeline is acceptable, and the delivery site including zone registration status if applicable (PEZA, SBMA, or standard VAT-registered). Photos of the existing unit's nameplate, if the replacement is for a failed installation, help confirm the specification match before a number is quoted rather than after. Buyers who can supply the original system design or booster pump specification sheet get the most accurate match, since the bladder tank's pressure rating needs to correspond to the pump curve and system demand, not just the physical footprint of the unit being replaced. Submitting this information in the first RFQ message, rather than piecemeal across several follow-ups, is what keeps the 1 business day response time realistic on JOHOB's side.
