Different wastewater pump manufacturers in New Zealand claim to produce the best pumps. But when choosing the right pump you shouldn’t involve emotions and buy from a company that has the best branding or a company that advertises too much on TV. You have to be rational and ensure you buy the right pump for your application. Here are some important things you should consider when buying a wastewater pump.
Types of wastewater pump
You need to know the different types of wastewater pump available. The most popular types are the grinder pumps and ejector pumps. These two types use different impellers and motors to develop flows. They also offer different housings to handle different sizes of solids. It is important to understand the solid material and the flow rate you want when choosing a suitable pump.
How impellers work
Top wastewater pump manufacturers in NZ will explain to you how impellers work. However, you need to do your own research. While grinder pumps have extra mechanical components that grind up the waste, solids handling pumps are made in a way that reduces contact between the rotating parts and the process material.
The type of impeller will determine how efficient your pump is and the issues that may arise such as corrosion resistance, wear and clog reduction.
Water quality
You should know the wastewater materials that you need to process when choosing the right wastewater pump. Granular particulates such as gravel or sand, chlorine level, pH balance and other important factors should be considered.
Impeller materials
When choosing wastewater pump manufacturers in NZ, you should ask them about the materials they use in constructing impellers. Ductile iron is a common material and it comes at a cheaper price. Unfortunately, it has a few limitations based on the quality of water. Stainless steel and bronze are more expensive and come with their drawbacks. However, they are abrasion, cavitation and chemical resistant.
