MY series

HIGH GRADESUBMERSIBLE SEWAGE PUMPS

SERIES MY

The MY-series of the “TSURUMI AVANT” brand features high grade submersible sewage pumps that Tsurumi makes. Designed and built with a heavy emphasis on durability and pumping efficiency, these high quality pumps are more reliable and run more stably than similar class pumps.

Moreover, to ensure users get what they are looking for, the MYseries offers 4 types of impellers (Open Channel, Vortex, Grinder and High Head) and a versatile range of specifications featuring 40 to 250 mm discharge bore diameters and 1.5 to 18.5 kW motor output specifications. A wide lineup of 2-pole motors that deliver the performance needed in high head applications is also available.

Characteristics

  • Cast iron structure
  • Three-phase motor from 1.5 to 18.5 kW
  • Insulation: class H (180°C)
  • Protection rating: IP68
  • 50 Hz and 60 Hz versions
  • Thermal protection devices incorporated in stator
  • AISI 431 drive shaft
  • Two silicon carbide mechanical seals in large oil chamber
  • Discharge from DN32 to DN250
  • Large free passage

Features

CABLE GLAND

CABLE GLAND

The universal GAS thread of the cable gland is able to take a sheathing pipe to protect the power cable from mechanical or chemical damage due to turbulence or the aggressive nature of the liquid.

PRESSURISED TESTING

PRESSURISED TESTING

Every model undergoes pressurised testing to guarantee perfect assembly and operation of the gaskets, cable gland and mechanical seals.

MECHANICAL SEALS

MECHANICAL SEALS

Double mechanical seals in silicon carbide (SiC-SiC) enclosed in an inspectable oil chamber. This prevents all contact between the mechanical seals and any solids or filaments in the wastewater.

MOTOR

MOTOR

Tsurumi MY-series is fitted with IP68 rated, high performance induction motor, specially designed for submersible pumps. They come with superior Class H insulation rated at 180°C, to prevent motor burn out and enabling the pump to handle 20 evenly distributed starts per hour.
The motor frame and assembly to the pump parts are specifically designed to improve heat exchange and subsequent cooling by means of the surrounding water. Capable of handling variable speed, all Tsurumi MY-series high efficiency motors are capable of utilizing the full available power.

SHAFT

SHAFT

Tsurumi MY-series uses SUS431 grade stainless steel for shaft material with superior strength, hardness and corrosion resistance properties than the usual SUS420 stainless steel.
For convenience during maintenance, the shaft has been tapered for easy assembly of the impeller.

SENSORS

SENSORS

Tsurumi MY-series pumps come with thermal sensors embedded on the stator windings which prevents the over-heating of the motor. Should the winding temperature of the motor rise to the actuating temperature of the sensor, it will cause the control panel to shut the power supply to the pump.

Electrode type leakage sensor is installed inside a large oil chamber to detect water incursion through the mechanical seal as a redundancy to prevent leakage into the motor chamber. (All 4-poles pump, and 2-poles pump above 2.2kW)

ANTI-CLOGGING SYSTEM

ANTI-CLOGGING SYSTEM MYBMYG

The special conformation of the hydraulic part ensures the expulsion of solids and prevents fouling of the impeller.

The special shape of a debossed groove in the hydraulic part ensures the non-clogging feature of the Tsurumi MY-series. Any solid or fibrous material that might get entangled and clogged in the impeller will be guided on to this groove and expelled through the grooved path. Due to the prevention of partial and soft clogging in the hydraulic parts, the performance is maintained throughout the operation cycle, without any compromise in flow and head.

PAINTING

PAINTING

Bi-component epoxy paint (200 μm) is used as standard for all Tsurumi MY-series pumps. This has better resistance to corrosion.

MATERIAL

MATERIAL

All the cast Iron parts used in Tsurumi MY-series pumps is in FC 250 grade, which is stronger and harder than cast iron parts of other pumps.

Mechanical Seal with two pairs of Silicon Carbide seal faces is enclosed in the oil chamber to prevent leakage into the oil chamber and subsequently to the motor chamber. Due to the hardness of Silicon Carbide, the abrasion of sealing faces is less significant, ensuring the sealing feature for long time.
