This document provides an installation and service manual for the DanPumps S-WP series of submersible wastewater pumps. These pumps are designed for various applications, including wet-pit, dry-pit, and portable installations.
The DanPumps S-WP series pumps are single-stage, non-self-priming pumps primarily designed for pumping water, wastewater containing pollutants, and low-viscosity types of sludge. They can also be utilized as drainage pumps in environments where sand and gravel may be present. The motor is built-in and operates in a 3-phased version, suitable for either 50 Hz or 60 Hz power supplies. The impeller design is customizable, allowing for trimming to meet specific performance requirements.
The pumps are equipped with several protective features to ensure reliable operation and longevity. A thermal protection switch is built into the electro motor, designed to open at 150°C and automatically close at 90°C, preventing overheating. Additionally, a moisture sensor is integrated into the pump, detecting moisture in both the stator and oil compartments. This sensor is connected to an external moisture relay in the main control box, which can either cut off power or signal an alarm upon moisture infiltration. For enhanced cooling, some pumps can be optionally fitted with an internal cooling jacket, which operates as a closed cooling circuit system to prevent clogging and maintain cooling efficiency.
The S-WP pumps are versatile and can be installed in three primary configurations:
For all installations, proper cable management is crucial to avoid sharp bends, squeezing, or entanglement. The discharge pipe dimensions should be appropriate for the required flow capacity, and connection elements that might cause air pockets should be avoided. The water speed in the pipes should ideally remain below 2 m/s.
Electrical installation must be performed by qualified specialists in accordance with local regulations. Before starting, all power must be switched off. The supply voltage and frequency must match the pump's rated data, with permissible deviations of ±5% voltage and ±2% frequency. A ground fault circuit breaker is mandatory, and the electric board must include a motor guard sized for the motor. The motor guard settings vary for direct on-line starting and star-delta starting, with adjustments for thermal surveillance connections. The moisture sensor conductor (D1) must be connected to a relay in the external control board.
During operation, the pump must be fully assembled and placed on a solid surface to prevent rotation or tipping due to the powerful starting torque. The rotation direction should be checked before starting; if incorrect, two phases must be switched in the external control box. The pump should never be started with incompletely connected cables or non-operational overload switches and leakage sensors.
Regular control and preventive maintenance are essential for the economical and reliable operation of the S-WP pumps. A check-up every 6 months is recommended, with more frequent inspections under extreme operating conditions. For a complete overhaul, an authorized DanPumps A/S workshop or local dealer should be contacted. Before any inspection, service, or repair, the pump must be physically disconnected from the electrical power supply.
Key maintenance procedures include:
All contact surfaces and O-ring grooves should be cleaned, and O-rings should be replaced and lubricated during reassembly to prevent damage and facilitate future servicing. Specific tightening torque values are provided for various screw sizes, and cable glands should be tightened until good resistance is felt, followed by one full rotation for each screw.
