The reason is always the same: PP is cheaper. It is understandable. But cheap is not always cheaper. A PP pump running with Nitric Acid 68% or […]
Why Engineers in Chemical Processing Keep Choosing AODD Pumps Over Centrifugal
Walk into any chemical plant, glove factory, or water treatment facility in Malaysia and you will find AODD pumps running. Not because they are the cheapest option. Not because they are the simplest. But because for a specific set of conditions — and those conditions are extremely common in chemical handling — they outperform the […]

Most AODD pump problems — premature diaphragm failure, poor flow rate, excessive air consumption, early seal wear — can be traced back to the selection stage. The wrong pump going into an application is a problem that no amount of maintenance will fix. Here are the five factors that must be considered before specifying an […]
