1 SQ, SQE, CU 331, and SP SQ, SQE introduction 1. SQ, SQE introduction 3-inch SQ, SQE submersible well pumps for 3-inch and larger wells SQ, SQE pumps are suitable for both continuous and intermittent operation for a variety of applications: • Domestic water supply • light commercial • irrigation • tank applications. Dry-running protection The pumps are protected against dry running.
1 Overvoltage and undervoltage protection The pump design features "floating" impellers (not fastened to the shaft). Each impeller has its own tungsten carbide/ceramic bearing. The construction and materials ensure high wear resistance to sand for long product life. Overvoltage and undervoltage may occur in case of unstable voltage supply. The integrated protection of all motors prevents damage to the motor in case the voltage moves outside the permissible voltage range.

2 SQ, SQE, CU 331, and SP SQ, SQE applications 2. SQ, SQE applications SQ with pressure switch and pressure tank SQ is ideally suited for domestic water supply in single-family dwellings or summer homes which are not connected to municipal waterworks. SQ is easy to install and operate.
2 SQ, SQE, CU 331, and SP SQ, SQE applications Constant-pressure control with CU 301, residential water supply The system maintains a constant pressure within the maximum pump performance in spite of a varying water consumption. The pressure is registered by the pressure sensor and transmitted to the CU 301. The CU 301 adjusts the pump performance accordingly. When the pressure in the tank is 7 psi (0.5 bar) below setpoint, the pump will start. The pump will run until the pressure is 7 psi (0.
2 SQ, SQE, CU 331, and SP SQ, SQE applications Constant-pressure control with CU 301, irrigation At a flow higher than approximately 1 gpm (0.18 m3/h), the pressure will drop quickly and the pump will start immediately and maintain a constant pressure. During operation, the CU 301 will regulate the pump speed to maintain a constant pressure. If there is no consumption, the pump will boost the pressure to 7 psi (0.5 bar) above setpoint and stop after a few seconds.
2 SQ, SQE, CU 331, and SP SQ, SQE applications Maintaining a constant water table A constant water table can be maintained by adjusting pump performance. It may be important to maintain a constant water table, e.g. in connection with keeping out the groundwater on a building site or water remediation projects. The example shows how to maintain a constant water table by adjusting pump performance. Sensors Level Description Reaction Level sensor (pos. 11) Warning (max.) Desired level Warning (min.

Operating modes Constant pressure with stop function These operating modes can be selected with the CU331SP: • Normal • Stop • Min. • Max. The operating modes can be set without changing the setpoint setting. The outlet pressure is kept constant at high flow rate (Q > Qmin). On/off operation at low flow rate. See fig. 25. The pump operates in constant pressure mode. Qmin The pump has been stopped by user.
10 SQ, SQE, CU 331, and SP CU331SP variable frequency drive Operating conditions for the stop function Setting the direction of rotation It is only possible to use the stop function if the system incorporates a pressure sensor, a non-return valve and a diaphragm tank. The non-return valve must always be installed before the pressure sensor. Diaphragm tank Pressure sensor The start-up guide is started the first time the CU331SP is connected to supply voltage.
Operating hours CU331SP installation The value of operating hours is an accumulated value calculated from the pump's startup date and cannot be reset. No additional sensor is required. Mechanical installation Sensor display will show the actual pressure as received from the pressure transducer. The individual CU331SP cabinet sizes are characterized by their enclosures. The table in section CU331SP technical data on page 49 shows the relationship of enclosure class and enclosure type.
10 SQ, SQE, CU 331, and SP CU331SP electrical connection CU331SP variable frequency drive Space requirements and air circulation TM03 8859 2607 CU331SP units can be mounted side by side, but as a sufficient air circulation is required for cooling these requirements must be met: • Sufficient free space above and below the CU331SP • Ambient temperature up to 122°F (50 °C) • Hang the CU331SP directly on the wall, or fit it with a back plate. See fig. 29. Fig.
Protection against overcurrent Mains connection The CU331SP has an internal overcurrent protection for overload protection on the motor output. Check that mains voltage and frequency correspond to the values on the nameplate of the CU331SP and the motor. Protection against mains voltage transients The CU331SP is protected against mains voltage transients according to EN 61800-3, second environment. Mains and motor connection The supply voltage and frequency are marked on the CU331SP nameplate.
10 SQ, SQE, CU 331, and SP 0/4-20 mA As a precaution, signal cables must be separated from other groups by reinforced insulation in their entire lengths. If no external on/off switch is connected, short-circuit terminals 18 and 20 using a short wire. RS-485 A GND Sensor 1 TM05 5802 3913 Jumper wire GND Start/stop Operation is only possible when the terminals 18 and 20 are connected, for instance by means of an external on/off switch or a short wire.
Setting the analog input 54 Access to signal terminals The contact A54 is positioned behind the control panel and is used for setting the signal type of the analog input. The factory setting of the inputs is voltage signal "U". This setting must be changed to "I" prior to starting the CU331SP. Be sure the power supply is switched off. All signal terminals are behind the terminal cover of the CU331SP front. Remove the terminal cover as shown in fig. 39.

12 SQ, SQE, CU 331, and SP SP introduction 12. SP introduction Introduction Applications The Grundfos SP range of submersible pumps is renowned for high efficiency and reliability. Made entirely of corrosion resistant stainless steel, SP pumps are ideal for a wide variety of applications. Grundfos SP pumps represent state-of-the-art hydraulic design.
A wide pump range Pump design Grundfos offers energy-efficient SP submersible pumps with a performance range of up to 1,400 gpm and 2,100 ft of head. The pump range consists of many pump sizes, and each pump size is available with an optional number of stages to match any duty point. Grundfos SP submersible pumps feature components that contribute to the superior performance and durability of the range.
12 SQ, SQE, CU 331, and SP Stop ring All pumps are equipped with a reliable check valve in the valve casing preventing back flow in connection with pump stoppage. Furthermore, the short closing time of the check valve means that the risk of destructive water hammer is reduced to a minimum. The valve casing is designed for optimum hydraulic properties to minimize the pressure loss across the valve and thus to contribute to the high efficiency of the pump. Note: As shown in fig.
12 SQ, SQE, CU 331, and SP SP introduction Grundfos submersible motors Grundfos offers a complete submersible motor range in different voltages. For an overview of motor types, sizes and voltages, see page 131. • MS 402 is designed for the domestic ground water market and covers outputs. • The MS 4000 and MS 6000C series are designed for use in a variety of applications in water supply.
12 SQ, SQE, CU 331, and SP SP introduction Overtemperature protection Built-in cooling chambers Accessories for protection against overtemperature are available for both Grundfos MS and MMS submersible motors. When the temperature becomes too high, the protection device will cut out so damage to the pump and motor can be avoided. Restart of the motor after cut-out can be achieved in two ways: • manual restart • automatic restart.
12 SQ, SQE, CU 331, and SP SP introduction Shaft seal MS 402 The shaft seal is of the lip seal type characterized by low friction against the rotor shaft. The rubber material offers good wear resistance, good elasticity and resistance to particles, and it is approved for use in drinking water. MS 4000 Ceramic/tungsten carbide materials provide the MS shaft seals with optimum sealing, optimum wear resistance and long life. MS 6000C TM00 7306 0412 The MS 6000C shaft seal material is SiC/SiC.
