May I ask, is it possible to modify the metering pump in this way?

Plunger-type metering pump model: J-W2.5/4, plunger diameter 8mm, motor power 180W. Since the injection volume cannot meet the process requirements even when set to its maximum, it is planned to change the plunger diameter to 12mm. Is this feasible? Do the motors need to be replaced?
The changes are too significant; the motor power is not sufficient.
You have a micro-dosing pump; Hangzhou Daquan Pump Industry Technology Co., Ltd. can assist you—website: hzdaquan.com—model: pj0.4-2.5/4, motor power of 0.18, plunger diameter of 6 mm.
It appears to be a micro dosing pump based on its model; how can it be identified in other ways? For example, in terms of plunger diameter and motor power?
Previously, domestic metering pump models were denoted by the initial consonants of their names in Pinyin, with J standing for metering pump; JW referred to metering pumps for small flow rates, JX to those for medium flow rates, and so on. :) Through decades of exploration and innovation, our company has completely transformed the traditional manufacturing techniques for metering pumps ； Leading in China, on par with the world. In terms of model selection, based on the plunger output force, the models available include 0.4, 1.6, 2.5, 5, 8, 12.5, 25, and 50; where 0.4 indicates a plunger output force of 400 Newtons per meter.
