Plastic Diaphragm Pump

Introduction to Plastic Diaphragm Pumps

Plastic diaphragm pumps are a class of pumps ideal for transferring fluids with low to high viscosity. These pumps utilize a flexible diaphragm that moves back and forth to create a temporary chamber, which draws in and expels fluid through the pump. The construction material and simple operating mechanism make them suitable for a variety of applications, from chemical processing to water treatment.

Types and Applications

There are several types of plastic diaphragm pumps, each designed to meet specific operational needs. Air-operated and electrically operated models are common, catering to different power source preferences. These pumps are widely used in industries such as pharmaceuticals, food and beverage, and manufacturing, where gentle handling of the product is crucial.

Features and Materials

The defining features of a plastic diaphragm pump include its corrosion-resistant body, usually made from high-grade plastics like polypropylene or PVDF. This makes them resistant to chemical wear and suitable for handling aggressive fluids. Additionally, their compact design allows for easy installation in limited spaces.

Advantages of Using Plastic Diaphragm Pumps

The advantages of using a plastic diaphragm pump are numerous. They are known for their dry running capabilities, good suction lift, and ability to handle sludges and slurries with ease. Their plastic construction also means they are lighter in weight and often more cost-effective than their metal counterparts.

Selection Criteria

When selecting a plastic diaphragm pump, it is important to consider factors such as the flow rate, which varies by model, and the compatibility of the pump materials with the fluid being handled. The pump's size and the nature of the application, whether it's for intermittent or continuous duty, also play a critical role in the selection process.
