Piston vacuum pumps are the economical choice for basic laboratory and industrial operations.
Piston pumps emphasize economy, durability, and basic functionality. Whereas other pump types (such as diaphragm and belt-drive pumps) are focused on providing chemical resistance and robust feature sets, the piston vacuum pump is designed to accommodate basic laboratory needs without breaking the bank.
