Features

• Non-clog impeller
  A single channel wide opening impeller allows the pump to handle suspended solids with the diameters up 80mm. This ensures that sewage andwastewater are transferred without clogging.

• OIL LIFTER (patent pending)
  The OIL LIFTER stabilises the function of the mechanical seal. It increases the life expectancy of the seal and extends the maintenance cycle. The OIL LIFTER is supplied on all BZ Series pumps.

• Dual inside mechanical seal
  The pump is furnished with a dual inside mechanical seal located completely in an oil chamber. This seal system does not rely on the pumped media for the lubrication and cooling, which increases the reliability of the sealing.

• Anti-wicking cable entry
  Every cabtyre cable has an anti-wicking block at the cable entry section of the pump. This unique feature protects the motor from the ingress of water that may be caused by damage to the sheath of the cable. Each pump up to 3.7kW has a rubber moulded cable entry, and pumps of 5.5kW or above has an epoxy-filled entry.

• Motor protection device
  Every pump has a motor protection device built in its motor. 3 miniature thermal protectors (MTP) are supplied on the pump as standard.

• Back pull system (Pumps up to 3.7kw)
  Unfastening the bolts between the oil casing and the pump casing allows the body to be separated into the pump section and the motor section with the impeller left in position. This makes the inspection or cleaning of the impeller easier.

• Guide rail fitting version
  Guide rail fitting readily connect/disconnect the pump to/from the piping system only by lifting up and down the pump, allowing easy maintenance and inspection without the need to enter the sump. Pumps in this version have a \"TOS\" identifier on top of their model codes.

• Shaft
  The stainless steel on all pump shafts is supported by C3 type, high quality deep groove ball bearings.

• Special Options

  Galvanic Corrosion Protection

  In sea water applications, Tsurumi can supply pumps with higher electrical potential sacrificial anodes so that these parts corrode before the pump material resulting in longer life span for the pump.

  High Temperature Liquid

  Standard pumps are designed for continuous running at a maximum temperature of 40°C. Two high temperature operating models are available. Rank 60 for operation in liquids up to 60°C and Rank 90 for operation in liquids up to 90°C.

  Different Materials

  Impellers, pump castings and suction covers can be made of stainless steel, chromium iron and bronze if required.

  Dry pit type pumps are an option for the whole BZ series range. A special motor plus a water jacket assures that the pump can continuously run dry without over heating.
