Every product shipped by IsoHiTech Lubrication Systems is covered by a straightforward warranty. This page explains the warranty period, what it covers, how to make a claim, and what happens after you contact us. IsoHiTech Lubrication Systems is a centralized lubrication system manufacturer founded in 2023, engineering since 2006, located at No.212 Ave. LanTian Road, Lukou Economical Park, Jiangning, Nanjing, China.
Warranty Period
Our standard warranty period is 12 months, starting from the date you receive the goods. This applies to the lubrication equipment we manufacture and supply, including grease pumps, oil lubrication pumps, progressive distributors, injectors, single-line and dual-line system components, fittings, and hoses.
What the Warranty Covers
The warranty covers problems that are on our side — manufacturing defects and failures that occur under normal installation and operation, within the rated parameters of the product. If a problem turns out to be our responsibility, the remedy is simple: we ship the required replacement parts to your location. You do not need to send the complete unit back to China before receiving parts; our goal is to get your lubrication system running again with the least possible downtime.
Problems caused by factors outside our responsibility — for example, installation that does not follow the product documentation, or operation outside the product’s rated pressure, temperature, or lubricant specification — are not warranty cases. If you are unsure whether your situation qualifies, contact us anyway; our engineers will tell you honestly which side the problem is on.
How to Make a Warranty Claim
The process is deliberately simple:
- Contact us at b2b@isohitech.com or WhatsApp +86 13814034409, with your order number or invoice reference.
- Describe the symptom — what the system is doing or not doing, when it started, and the operating conditions. Photos or a short video of the pump, metering block, or fitting in question help our engineers diagnose much faster.
- Diagnosis — our engineering team reviews the information and confirms the cause. In many cases we can also guide your maintenance staff through an on-site check at the same time.
- Resolution — if the problem is our responsibility, we ship the replacement parts to you. If it is not a warranty case, we still help: we quote the parts you need and provide repair guidance so your system is back in service quickly.
Beyond the Warranty Period
A lubrication system is a long-life asset, and our support does not end at month 12. After the warranty period, you can continue to order spare parts from us — pump elements, metering blocks, injectors, seals, hoses, and fittings — and our engineers remain available for technical questions about systems we supplied. Keeping your model and order records makes future spare-parts matching fast and accurate.
