HS 5530.181

Summary

Product identification

The 5530 and 5540 are submersible, electric motor-driven pumps intended for:

• Pumping of water which may contain abrasive particles
• Pumping of sludge
• Pumping of ground water
• Pumping of light slurries

The pump is available in the following versions:

• HP: For permanent installation in a sump, sliding down a guide arrangement and connecting automatically to a discharge connection.
• HS: Transportable version with a stand and connection for hose or pipe.
• HT: For a vertical dry stationary installation on a stand, directly connected to the inlet and outlet lines.
• HZ: For a horizontal dry stationary installation on a sled, directly connected to the inlet and outlet lines.

Operating limits

• Liquid temperature: Max. 40°C (105°F). Versions for liquid temperatures up to 70°C are available, with specific operational limitations stated on the pump plate.
• Liquid density: Depending on the duty point.
• pH of pumped liquid: 6—14
• Lowest liquid level: Above the pump
• Depth of immersion: Max. 20 m (65 ft)
• Environmental restrictions: The pump may not be used in an explosive or flammable environment or for pumping flammable liquids.
• Motor operation: Can be run continuously or intermittently with a maximum of 15 evenly spaced starts per hour.
• Voltage variation: Rated output is supplied at ± 5 % variation of the rated voltage. Without overheating, ± 10 % variation of the rated voltage can be accepted provided the motor does not run continuously at full load.
• Voltage imbalance: Designed to operate with a voltage imbalance of up to 2 % between the phases.

Electrical

The pumps feature a squirrel-cage 3-phase induction motor for 50 Hz or 60 Hz, started by direct on-line or star-delta start. The stator is insulated in accordance with class F (155°C, 310°F).

Rated Output:

• 5530.181:
  • 50 Hz: 5.9 kW, for HP/HS-version
  • 60 Hz: 10 hp (7.6 kW), for HP/HS-version
• 5540.181:
  • 50 Hz: 13.5 kW, for HP/HS-version
  • 50 Hz: 13.5 kW, for HT/HZ-version (with external cooling)
  • 60 Hz: 20 hp (14.9 kW), for HP/HS-version
  • 60 Hz: 20 hp (14.9 kW), for HT/HZ-version (with external cooling)

Motor Data (Rated and Starting Currents): See the official PDF for exact tabulated values for voltage, rated current, and starting current across various 50 Hz and 60 Hz configurations (5.9 kW, 10 hp, 13.5 kW, 20 hp) and voltages (e.g., 220 V, 380 V, 415 V, 500 V, 660 V for 50 Hz; 230 V, 460 V, 575 V, 600 V for 60 Hz).

Monitoring Equipment:

• Three thermistors, connected in series, are incorporated in the stator. Resistance changes at 130°C (266°F).
• A platinum transducer (Pt 100) per phase registers the winding temperature.
• Three thermal switches, connected in series, are incorporated in the stator, opening at 125°C (260°F).
• Thermal switches for the warm liquid version shall not be connected when the liquid temperature is above 40°C (105°F).
• Monitoring equipment must be designed to prevent automatic restart.
• Leakage sensors are available for sensing water in the oil and/or stator housing.

Mechanical / hydraulic

Design: The motor is cooled by the surrounding liquid. The pump must work fully submerged under full load conditions; otherwise, external cooling must be used. The minimum flow of external cooling water is 18 l/min. The 5530.181 is not available with external cooling.

Materials:

• Major Castings, Outer Casing, Cooling Jacket, Hydraulic Casing: Cast Iron (e.g., DIN 1691 GG 25, ASTM A 48 Grade No 35 B)
• Screws, Studs and Nuts: Stainless Steel (e.g., AISI X5CrNi 18 10, ASTM Type 304)
• Impeller, Wear Parts: Alloyed White Cast Iron (e.g., DIN 1695 G-X260 Cr 27)
• Strainer: Steel (e.g., DIN 17100 RST 37-2)
• Lifting Handle: Galvanized Steel (e.g., DIN 17100 RST 37-2)
• Shaft (5530): Stainless Steel (e.g., X20 Cr 13)
• Shaft (5540): Stainless Steel (e.g., 17440 X22 CrNi 17)
• O-Ring (Std-version): Nitrile Rubber 70°IRH
• O-Ring (Warm-liquid version): Fluorinated Rubber 75°IRH

Surface Treatment:

• Impeller: Sprayed with a primer.
• Outer Casing: After priming, coated with black chlorinated rubber paint.

Bearings: The pump bearings are designed for at least 50 000 hours of operation.

• Support bearing: Single ball bearing for 5530, roller bearing for 5540.
• Main bearing: Two-row angular contact ball bearing.

Shaft Seals: The pump has two mechanical seals with extremely wear-resistant seal surfaces.

• Inner Stationary/Rotating: Tungsten carbide, WCCR
• Outer Stationary/Rotating: Tungsten carbide, WCCR

Oil Casing: The oil lubricates and cools the seals and acts as a buffer between the pump casing and the electric motor. Pressure build-up within the oil casing is reduced by a built-in air volume.

Shaft: The shaft is delivered with the rotor as an integral part and is made of stainless steel.

Impellers: The pump is available with a shrouded three-channel type impeller made of high chrome alloyed white cast iron (HC). The throughlet is 40 mm.

Wear Parts:

• Impeller
• Wear lining
• Wear ring
• Wear cover
• Suction cover
• Trimming flange
• Pumping housing

Flushing: External flushing of the outer seal can be connected to one of the holes (1/2″ thread must be cut). Required flow is 1—3 l/min and a pressure of 5 m + shut-off head.

Weights (without motor cable, in kg (lb)):

• Pump unit 5530: 203 (448) HC
• Pump unit 5540: 284 (626) HC
• Pump unit with cooling jacket 5540: 298 (657) HC
• Stationary Discharge Connection: 85 (187) HC
• In-/outlet Elbow: 38 (84) HC
• HT/HS Stand: 30 (66)
• HZ Sled: 125 (275)
• Frame and Access Cover: 29 (64) (HC = High Chrome Alloyed with Cast Iron)

Performance: Each pump is tested in accordance with ISO 2548 class C standard. See the official PDF for performance curves and best operating points. An agitator, if present, draws an extra power of 0.7 kW (50 Hz) or 1.2 kW (60 Hz).

Dimensions: See the official PDF for detailed dimensional drawings and tables for HP, HS, HT, and HZ versions, with all dimensions in mm (in).
