THE ADVANTAGE OF DESIGN. This robust pump technology is especially advantageous for many applications that require low pressure (up to a maximum of 0.8 MPa/120 psi). The PUMP is a mechanically driven diaphragm pump that is highly energy efficient, because the drive does not require expensive compressed air. Its compact, special design does not require hydraulic fluid, and it can be suitably equipped to provide the performance required by each specific application. The Electromechanical Diaphragm Pump’s unique design concept and impressively low energy consumption when used in the most diverse of applications by the most demanding of customers have helped solidify Harish Techno’s good reputation.
