SMART Digital XL pumps combine high-precision dosing with unsurpassed user-friendliness. Stepper-motor technology greatly improves the level of control when compared to traditional metering pumps. Their variable-speed motor remains in contact with the diaphragm throughout the entire discharge/suction cycle‚ controlling its speed at all times. Modular control panels allow for front or side mounting.

The stepper motor runs continuously‚ ensuring that the discharge phase extends throughout the period between suction phases. This provides a more even mix. The motor automatically adjusts the dosing speed to provide the right amount of additive at all times. Thanks to their smooth digital dosing‚ time between service periods is more than doubled. Pumps use a full stroke length every time they pump for added accuracy and efficiency. The stroke speed is automatically adjusted to ensure even concentrations.

DDE models are the most economical option. Pump features pulse input controls. Manual control models are also available.

Use with 37% hydrochloric acid*‚ 20% sodium hypochlorite and 98% sulfuric acid*. Wetted materials: PVDF body‚ Teflon diaphragm‚ FKM O-rings and ceramic check balls. *We recommend hard-piping for all acid applications.

XL Series Pumps include: control cable for pulse and/or 4-20 mA input.
