Dosing & Metering Pumps NZ – Peristaltic, Solenoid & Diaphragm | HD Process
For applications requiring accurate, repeatable dosing, HD Process supplies a comprehensive range of metering pumps. Our portfolio includes peristaltic pumps that gently move viscous or shear‑sensitive media, solenoid‑driven pumps for low‑flow chemical dosing, lobe metering pumps for hygienic product additions and diaphragm pumps offering precise constant or jet‑pulse delivery. These units provide reliable control of flow rates across a wide range of viscosities and pressures.
Constructed from chemical‑resistant materials and available with hygienic or industrial designs, the pumps support flexible installation and integration into process control systems. Options include manual or automatic stroke adjustment, digital interfaces and CIP‑compatible configurations. Whatever your dosing challenge, HD Process can recommend a solution tailored to your product, viscosity and flow requirements.
