The Masdaf MDP vertical borehole pump is a column-type pump with a long shaft, designed for sumps and boreholes. The manufacturer classifies it as a column-type borehole pump. Operating range: flow rate 10\u2013210 m\u00b3\/h, head 4\u201365 m, speed 1,500\u20133,000 rpm, fluid temperature 0\u201390 \u00b0C.<\/p>\n

How does MDP differ from PS\/PSH?<\/h2>\n

Both series are vertical pumps with long shafts, but they are designed for different applications.<\/p>\n

MDP offers an order of magnitude greater flow rate, three times the head and operation at temperatures up to 90 \u00b0C. PS\/PSH handles small volumes at a single fixed speed. If the sump is small and the fluid is cold, there\u2019s no point in paying extra for an MDP; if you need a head of more than 19 m or hot fluid, there\u2019s only one option.<\/p>\n

To be confirmed upon request:<\/strong> the operating pressure of the casing, the impeller diameter for a specific operating point, the length of the riser to match the depth of the wellbore, the materials of construction, and the operating speed within the specified range.<\/p>\n

Design features<\/h2>\n

Securing the housing and the bearing ensures that the column, the suction cover and the bearing assembly remain parallel \u2014 the service life of the long shaft depends on this.<\/p>\n

The impeller is balanced to ISO G 6.3. The design of the impeller and the spiral casing is intended to allow solid particles to pass through unimpeded.<\/p>\n

Roller bearings are fitted in the pump inlet area to accommodate radial loads. A mechanical seal isolates the bearing assembly and the shaft surface from the fluid being pumped.<\/p>\n
