- Sanitary/hygienic designs are available optionally
With the edge of engineering response capability and reliability based on long years of rich accomplishments as well as the accomplishment of a high degree of injection accuracy and a long service life, the pumps are used in a wide variety of fields such as petrochemical, petroleum refinery, electric power, pharmaceutical, water supply and sewerage, and industrial liquid waste treatment.
PICK UPFlexible liquid mixing by precision control
With Nikkiso-LEWA-specific intelligent drive technology, the servo motor controls the piston movement with its position information and has complex control over the discharge flow of the reciprocating pump. A duplex or triplex system allows for pulseless flow Both hydraulic diaphragm pumps and mechanical diaphragm pumps are available.
- Multi-function mixing of two liquids
- Feeding high-viscosity liquid
- Precision filling
- Wide turndown ratio
Mixing two liquids with one pump
The an intelldrive pump can suck liquid 1 and liquid 2 in sequence and discharge the mixed liquid. The liquid mixing ratio can be adjusted with the controller. The discharge of liquid mixture can be adjusted with the speed pump.
Feeding high-viscosity liquid
The unit is capable of sucking high-viscosity liquid slowly and discharging quickly. Unlike conventional pumps, a large pump head is not required.
When the discharge fluctuates
For variable flow range
Downtime can be minimized in extrusion molding and other fields。

Hygienic pumps with improved
High-precision micro flow pumps for extremely low flow
Intellidrive capable of controlling the discharge flow at will
The servo motor controls the action of the piston with freedom and has complex control over the discharge flow by obtaining accurate stroke location information. A double or triple headed pump system allows for pulse free operation. Both hydraulic diaphragm pumps and mechanically actuated diaphragm pumps are available.
By controlling two pumps with intelldrive technology, it is possible reduce the pulsation in comparison to the conventional triplex pump.
