It is important to choose the pump according to the features of the final product. If you want to avoid the contact of the filling material with the spring, you should choose the spring outside pump.
Based on the features of the product you also have to decide about the dosage of the pump. Also keep in mind the viscosity of the filling material.
You should also choose your plastic pump in line with the current trends, to catch the customers eyes. In our webshop you can find various pumps in different shapes and colours. The style of the pump should also harmonize with the other parts of the packaging such as bottle.
Always take into consideration the technical parameters of the pump as well. Make sure to choose the correct neck size and dip tube length.
