Flood Control Pumps

The art of flood protection The threat of floods has been part of our lives ever since mankind changed their nomadic ways and decided to settle in certain places. Obviously some parts of the world are more prone to floods than others, but it has been a global problem throughout history and it is still affecting people all over the world today. Recent images from central Europe show that ...

Controlling the Flow Capacity of a Metering Pump

Since a metering pump is usually a positive displacement pump there are two possible ways of controlling the flow capacity. The first one is by adjusting the volume of liquid displaced per stroke of the pump and the second is by adjusting the speed of the strokes. I. Stroke Length – control the displacement volume per stroke II. Speed of Strokes per minute Stroke Length ...

Flood control pumps: Renovation of a pumping station in the Dutch polder

Flood control is an important issue for the Netherlands as the largest part of its surface area is vulnerable to flooding. Water control boards are the independent local government bodies responsible for maintaining Flood Protection Systems. In the Dutch region of Overijssel the local Water Board governs the water in the Agricultural polders. One of their refurbishment projects concerns a ...

A robust approach based on time variable trigger levels for pump control

An approach for the control of a pumping plant feeding a tank at the inlet of a water distribution system is presented. The approach is aimed at minimizing the energy costs by maximizing pumping during off-peak electricity tariff periods. It is based on trigger levels which are variable during the day according to a prefixed pattern in order to ensure that the water level in the elevated tank ...

Fuzzy maximum power extraction control for a photovoltaic water pumping system

AC loads present a delicate matter for photovoltaic systems, and this is because of the photovoltaic panel's operating point, which moves randomly according to irradiance changes; in this case, almost of photovoltaic water pumping systems use a DC–DC converter to ensure either the maximum power extracted from PV panel or the load needs. For AC motor pumps, an inverter must follow this chopper. ...

Principles of Solids Control

Although the use of drilling fluids within the HDD / trenchless industry is still relatively new, recent trends suggest that this standard is shifting as solids control is one of the most important phases in the drilling process. This shift is due to a growing awareness that drilling fluid maintenance and disposal can become exponential problems as they are both harmful to the environment and ...

How can I finely control the vacuum applied by my vacuum pump or system?

Some vacuum pumps or built in vacuum systems do not allow fine control over the vacuum applied. For rough work like vacuum filtration this is not always needed, but for more sensitive work, for example when using a rotary evaporator, application of the correct vacuum level is essential to smooth operation. The new ...

Programmable Syringe Pump

Chemical and biomedical researchers use the programmable syringe pumps for infusing and withdrawing small amounts of fluid. It helps to mix, separate, and process microfluidics in high precision experiments. Further, it reduces error in biomedical and chemical experiments by providing better infusion control to researchers. The programming ability of syringe pumps help researchers to precisely ...

What is a Syringe Pump?

A syringe pump is a type of infusion pump originally developed to help administer drugs to patients in a controlled manner. Early attempts to construct infusion pumps were made in the 19th century. However, the first infusion device was introduced in the 1950s to be used in chemotherapy. In the 1970s, the development of ambulatory infusion technology enabled the pumps to be used in research; ...

VFD for pumping systems

Pumping systems account for nearly 20% of the world's electrical energy usage. In some process plants, the VFD for pumps and fans together account for between 50% and 80% of the total electricity used. Very rarely have I come across pumps operating with fully open discharge valves. The same is the case for fans with dampers. ...

Industrial Pump Inspection

An industrial pump service and remanufacturing company had two goals in mind when they went shopping for a borescope. First, the scope had to be easy to use and portable enough to take on service calls. Second, it had to have four-way camera articulation in order to steer navigate the pipes and small through-holes that are commonly found in industrial pump applications. They found exactly what ...

Odour control on waste water treatment plants and pumping stations using DMT biotrickling filtration

Lengthy detention times and warm weather / climate leads to septic waste water producing copious amounts of not only hydrogen sulphide, but also ammonia, organic sulphides, mercaptans, bringing numerous odour complaints on waste water treatment plants ( WWTP’s ) and pumping stations. An odour abatement unit therefore will have to treat not only hydrogen sulphide, but also other pollutants ...
