VERTICAL SHAFT SEWAGE PUMPS
Submersible drainage sump pump made of stainless steel AISI 304, shaft sealing is with doublelip seals that run on a ceramic-coated shaft. Suitable for draining wells, plant room sumps, andemptying lift shafts, pools, sumps, small-scale irrigation and small water displays and pub cellars.Options include with or without float switch - VOX versions and 110 – 230 – 400V versions.
APPLICATIONS FEATURES• Can be used for pumping sewage containing • High-efficiency, non-clogging impeller can handle sewage
small solids and residue in small amounts containing small amount of small solids.directly into sewers, and is ideal as a general • Requires only small installation area. Pump is vertical type,waste water pump. so takes up only a small space and is convenient to handle.
• Trouble free operation. Repairing pumps of this type is aSTANDARD ACCESSORIES difficult business, so every care has been taken in theAnchor bolts : 1 set design to ensure trouble-free operation. The bearings andCompanion : 1 set their boiling system are of the most reliable type.Coupling : 1 set • Thorough prevention of foul odours and leaks. HermiticallyOiler (with tube) : 1 set sealed structure eliminates foul odours. There is no seepage
of sewage through glands or other joints, so floors stay clean.

FEATURES1. Water ring type which performs well even if liquid is
mixed with air.2. Rotary type with no contacting parts except for
bearings and shaft seal provides for efficient operationand maintenance, with less chance for malfunctions.
3. Great flexibility permitted for layouts due to compact lightweight construction.
4. Stable operation possible under high vacuum conditions.5. Type NVD combines pump and feed water tank in one unit
so that water is automatically supplied to the vacuum pumpto reduce noise.Also available, an exclusive feed water tank for Type NV.

[Question]How long will it take to lower the pressure of air in 10m3
container to – 6m using a pump of 50 NV 5.5kW capacity?[Answer]Intersecting point of – 6m and 50 NV 5.5kW reads17sec/m3. Therefore, the time it takes should be 17sec/m3
x10m3 = 170 seconds = 2 minutes 50 seconds.

STRAINERS RESISTANCE CURVE
Notes:1. The above resistance curves are approximate. Allow for variation of about 20%.2. Be sure to take strainer resistance into account when considering pump suction capacity.3. It is best if strainer resistance is less than 0.3 kgf/cm2. If it exceeds this value, use a strainer one size larger and make
suction pipes correspondingly thicker.*1kgf/cm2 = 98.0665kPa
OIL VISCOSITY CHART
PIPING RESISTANCEHow to read the chart
1. Follow the line of the required capacity towards the right,till it meets the piping diameter line (on which diameteris marked in inches).
2. Move straight down from the meeting point of the lines,till you reach the reference line (indicated by an arrow).
3. Follow the diagonal line that runs through the point onthe reference line (either upwards or downwardsdepending on the line) until you come to a (horizontal)viscosity (Redwood-seconds, RWS) line. Then drop aline straight downward from the intersection to the frictionloss on the scale at the bottom of the chart, and read offthe value.
Example:
1. When capacity is 100m3/h, piping diameter is 6E andRWS is 2000, friction loss will be 0.1 kgf/cm2 per 10mof piping
2. When capacity is 5 m3/h, piping diameter is 1E and RWSis 400, friction loss will be1 kgf/cm2 per 10m of piping

APPROXIMATE RESISTANCE OF PIPING TO KEROSENE
STRAINERS RESISTANCE CURVES
Specifications• Mesh: 60• Effective filtration area:
More than 3 times nominal inlet diameterModels STU & STW: More than 8 times nominalinlet diameter
• Case hydro test pressure: 6 kgf/cm2
• Max. normal pressure: 3 kgf/cm2
For details of model STU single strainer andmodel STW duplex strainer, see data sheetsfor Model GP.
Example:
When capacity is 20 l/min, piping size is 1/2B and kerosene temperature
is 0°C, friction losss will be 0.3 kgf/cm2 per 10 m of piping.
Note:
1. The above curves are for kerosene at normal temperature and areonly intended to be approximate.
2. Take these strainer resistance values into account when consideringpump suction performance.
3. For 12 & 15GPA pumps, use strainers of diameter 15mm. For 20 &25GPA pumps, use strainer of diameter 25mm.
