SP and SPA, with submersible motors, types Grundfos MS/MMS. Storage temperature If the pump is fitted with a motor of another brand than Grundfos MS or MMS, note that the motor data may differ from the data Pump: -20 - +60 °C.
If liquids with a viscosity higher than that of water are to be Sound pressure level of motors pumped, contact Grundfos. The sound pressure level of Grundfos MS and MMS motors is N EN 1.4401 and R EN 1.4539 grade stainless steel pump sets lower than 70 dB(A).
- Wear personal protective equipment. The use of a sine-wave filter is mandatory when operating an SPE pump set. Grundfos recommends to fit a 30 cm long pipe to the Fig. 3 Motor position during filling - MS4000 and MS402 pump to facilitate handling of the pump during installation.
5.1.3 Grundfos MMS6, MMS8000, MMS10000 and MMS12000 5.2 Positional requirements motors WARNING Filling procedure: Crushing of hands Place the motor at a 45 ° angle with the top of the motor upwards. Death or serious personal injury See fig. 5.
The maximum liquid temperature and the minimum flow velocity Q x 353 past the motor appear from the following table. [m/s] Grundfos recommends installing the motor above the well screen in order to achieve proper motor cooling via liquid passing the Flow rate motor.
MP 204 motor protection unit and contactor(s). 6.1.3 Required settings of motor-protective circuit breaker For motors with an MP 204 motor protection unit, Grundfos recommends using a special trip curve with P-characteristics at a setting of Un times 5 for 1 second.
I × 1.73 × 100 × Grundfos supplies submersible drop cables for a wide range of installations. A cable sizing tool is available on Grundfos Insite at: Length of submersible drop cable [m] https://www.grundfos.com/sp-system/download-sp-app-html. Rated voltage [V] ΔU...
Grundfos control box SA-SPM 50 Hz or 60 Hz without motor protection. MS4000, MS6000 3-wire single-phase motors must be connected to the mains via a Grundfos SA-SPM 50 Hz or 60 Hz control box incorporating motor protection. Fig. 10 2-wire motors When a conventional motor-protective circuit breaker is used, the electrical connection must be carried out as described below.
(and consequently the speed) to such a level that the necessary flow of cooling liquid past the http://net.grundfos.com/qr/i/98870684 motor is no longer ensured. enable the monitoring of the motor temperature, Grundfos recommend that Pt100 or Pt1000 sensor is installed.
8. Mechanical installation 8.3 Lifting the product Grundfos recommends to fit a maximum 30 cm long pipe to the WARNING pump to facilitate handling of the pump during installation. Sharp element Death or serious personal injury - When mounting the facilitating pipe, wear personal protective equipment to avoid cutting on sharp edges on the pump.
When flanged pipes are used, the flanges must be slotted to take Grundfos recommends checking the borehole by means of an the submersible drop cable and a water indicator hose, if fitted. inside calliper before lowering the pump to ensure unobstructed passage.
If the pump can pump more than yielded by the well, we • Maximum 15 per day. MMS12000 recommend that you install the Grundfos MP 204 motor protector • Grundfos recommends or some other type of dry-running protection. minimum 1 per year.
