MILROYAL Series B
Modular Metering Pump or Accurate Chemical Injection
The “V” Series pump is a range of compact, self-contained, pneumatic metering pumps suitable for injecting a wide variety of chemiå√cals that range from 0.07 gph to 9 gph (0.27 lph to 34 lph) and pressures up to 13,100 psig (903 barg).
Often used in oil & gas applications requiring micro-injection of neat chemicals, the CP125V125 model is capable of injecting volumes as low as 0.025 cc/stroke at pressures up to 8000 psig (552 barg). This makes it an ideal niche pump for extreme applications.
Made of 316 SS, the “V” Series pumps are robust and capable of meeting the toughest challenges.
