Sizing and Selecting the Proper Metering Pump: Part 1 of 2
A typical agriculture or process application can consume large amounts of chemicals during daily operations. While the volumes may be large, though, they must also be very precise, with exact amounts delivered according to strict injection schedules. The pressures—from very high to very low—that the chemicals are injected at must also be governed precisely. This demand for precise ...

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 – Manual: ...

Qdos metering pumps solve turbidity testing dilemma for Welsh Water
Until recently, turbidity testing at the Pontsticill Water Treatment Works in the Brecon Beacons National Park relied on the use of bellows pump technology. However, the inherent introduction of air in the samples was undesirable and led to false readings. Now though, relief has arrived in the shape Watson-Marlow’s new Qdos 30 metering pumps, which not only provide excellent suction ...

Dewatering Crews Keep the Alameda Corridor Dry and Open for Business
Griffin installed a multitude of deep wells along the alignment of the proposed railway to allow for construction. The discharge from the wells was pumped via large diameter high density polyethylene pipe (HDPE) to a below grade mixing vault, where a neutralizing agent was introduced to the groundwater as the quality of the groundwater was not allowed to discharge to the designated receiving ...
