Capacity to control minimum displacement The DELTA pumps are designed to regulate flow from maximum flow to flow cancellation mode. However, some applications require a minimum outlet flow to be maintained, regardless of how flow is controlled from maximum to minimum. Capacity to have a high speed rotation The rotating speed of the DELTA pumps depends on: • flow supplied by the pump, • the fluid viscosity, • the pressure at inlet point of the pump. For applications at higher speeds than those indicated, please contact our Technical Department with details of these parameters, to enable us to advise what can be recommended. ■ Features of DELTA pumps The DELTA pumps are equipped with a maximum displacement control.
