Page 10: Bladder Pump Operation In Low-Submergence Applications
In wells in which this water column height is 5 feet or less, the pump is considered to be in a low-submergence application. QED sampling bladder pumps fill by hydrostatic pressure. As the inside of the pump's bladder fills with water, the bladder expands. This filling and expanding of the bladder is referred to as the "refill"... -
Page 11: Turning The Mp50 On
The MP50 displays an opening screen for 5 seconds, after which it displays the default Micro- Purge screen. At this point the MP50 is in MicroPurge mode (MP) but not cycling the pump. This initial state allows the user to adjust time and throttle settings before the pump starts to operate. -
Page 12: Micropurge Mode
MicroPurge Mode Most MP50 users will leave the controller in the default MicroPurge (MP) mode. See Figure 2 for an example of the MP50 in MP mode. MP mode lets you to use the UP and DOWN keys to directly increase and decrease pump flow rates. The MP50 has a broad range of other CPM settings to ensure the availability of a time setting that will match your specific conditions. - Page 13 Operation With this method, the number of complete pump cycles per minute is fixed, within a range of 1 to 6; 4 CPM is the default value which appears at startup. Each time the up/down arrow keys are pressed, the pump refill and discharge times are both automatically adjusted to maintain the selected CPM value.
