Are you left or right handed person? Either way, imagine trying to write using your opposite hand, the words won’t be written as good as your normal writing. Same is true when it comes to choosing the right dosing pump. The outcome upon setting up your dosing system must be exactly what you require for dosing fluids or chemicals or even water.
As you may know that dosing pump has the primary function of moving an exact and specific amount of fluids (into water, chemicals, gas or steam). This process is known as ‘metering’ as a result dosing pumps are also called metering pumps. There are many factors that go into choosing the right dosing pump for your requirements while also staying within budget.
Ideally, the pump should be chosen according to the pressure it can exert, the temperatures it can stand, and should be compatible with the fluids that need to be dosed. In some cases, these factors are neglected or ignored and this can result in serious accidents because most often times dosing pumps are used with chemicals.
It is worthwhile to note that if you are dosing fluids of a considerable temperature, you will need to be wary of the dosing pipes that you are using. Strong metal or PVF2 performs generally better in these conditions when compared with plastic.
PVDF: (PVF2 or Polyvinylidene fluoride) is a semi-crystalline high purity thermoplastic fluoropolymer with service temperatures up to 150°C and has these properties
- Chemical resistant
- High mechanical strength
- Piezoelectric and pyroelectric properties
- Great processability
Know Your Trade
Dosing pumps are used for a variety of purposes in diverse set of applications such as for treating wastewater treatment, pulp and paper, electroplating, textile, industrial effluent, which is why you need to be well-versed on the specifications of your particular requirements. WRS experts can answer all your questions and help you choose the best dosing pumps for your particular type of use. Contact us here
That being said, and because the metering pump market has many different types and models of pumps, it is not always the expensive dosing pumps that are the best nor can fulfill the purpose. But surely, for tasks in which exact measurements or high steady flow rates are not required, you can always use a cheaper dosing pump.
The Need for Customisation
Some metering systems can get quite complex to say the least. Within each system there are always other parts which completed the whole. Top quality dosing pump is just a missing piece that completes the function of metering. What is really required is a thorough system setup that is safe and performs well without downtime on productivity. Dosing pumps often require customisable parts such as pipes and enclosures in order to be suitable for on-site use.
Small mistakes such as placing a dosing cabinet or materials too close to an electric motor or heat can be disastrous. Best option for setting up complex systems always is with going through over your requirements, plans of your workplace or plant (or otherwise) with a professional and thus decide on the best pump model, location for your dosing pump and its parts.
Certain industries require pump configuration, materials, and accessories due to the exact nature of their application. It is best to know these in advance before you consider different dosing pump models.
The Dynamics of the Flow Rate
The flow rate is one of the most important functions of a dosing pump, and also a major determinant of whether a particular dosing pump is the right fit for the application. Typically the flow rate is measured via gallons per minute or per hour (in United Kingdom and Australia litre measurement is used), but there can be other measurements too.
Generally, the flow rate should be adjusted at a 90% capacity so that there is a subsistence level behind to make adjustments with. The higher the flow rate requires durable pumps, MB Series Motor Driven Chemical Dosing Pump by WRS is a great solution for these types of operations offering you a flow-rate 240 ~ 1800 (LPH)
The Nature of the Pumping Fluid
This is the second most important consideration when you are choosing a dosing pump. The type and size of the pump will in no small way be determined by the corrosive or high-temperature qualities of the fluid you need to dispense. The consistency of the fluid such as its weight, thickness, or whether it contains solids or its type (such as acid), will also weigh in on your decision.
