  • Page 3 1. Introduction. 1.1. Previous considerations Safety symbol. This symbol on the present document states that point described thereafter involves very important information regarding the safety of the vacuum pump operation The vacuum pump is one component of the vacuum unit (tanker). It is totally necessary to read the operation booklet provided by the tank manufacturer before operating with the pump and the tanker.
  • Page 4 1.2. General description The KL-18 vacuum pump is a rotary blade pump on eccentric rotor indicated for vacuum tankers. Its double body distributor together with the big displacement and the cooling system with an incorporated and external water pump configure an ideal set to work with big volume tankers and heavy-duty operations.
  • Page 5 2. Setting up. Always be careful by hanging the vacuum pump. Use the hole situated at the top of the pump body to lift the pump, keeping always the safety distance to avoid injuries due to a sudden fall down of the pump. 2.1.
  • Page 6 The overflow valve (3) guarantees that while filling up the tank the liquid cannot get into the vacuum pump. Anyway, a setting up of one siphon valve (2) is highly recommended in order to be sure that no liquid comes into the vacuum pump. The vacuum pipe must be of Ø...
  • Page 7 2.2 Cooling circuit description. In order to guarantee the best working conditions of the KL-18 vacuum pump, it is necessary to install a cooling circuit similar to the one shown in the following diagram: Filling plug Intercooler Drain plug Cooling liquid...
  • Page 8 Warning! It is not recommended to use the KL-18 without any cooling liquid on the chamber, as this can damage the vacuum pump body.
  • Page 9 In order to drain the air of the cooling chamber, the vacuum pump has a drain plug at the top of the body. PURGER This plug allows the air drainage while first filling and must not be manipulated thereafter: it has to stay at close position. Warning! The cooling chamber can come to very high temperature, close to 100 º, so a safety distance to the plug has to be kept just in case of some liquid damp expulsion...
  • Page 10 Final consideration: The continuous working time of a KL-18 vacuum pump is similar to the continuous working time of a normal rotary vanes vacuum pump. Once the pump has come to its maximal vacuum rate (close to 95% - 40 mm Hg) it has to be stopped in order to prevent any damage due to an overheating.

  • Page 11: Pump Operation

    3. Pump operation. Maximal angle between cardan shaft axe and pump shaft should not exceed 15º for 540 rpm pumps and 7º for 1000 rpm pumps. Never manipulate the pump when the cardan shaft or driven system is connected to the vacuum pump. Vacuum / pressure phases are regulated by handle J.

  • Page 12: First Operation

    (Picture 1) 3.1 First operation. KL-18 pumps always run counter-clockwise sense, as stated at the front cover. Be sure that driven system (cardan shaft or similar) turns on the right sense. Pump coupling F has to be connected and secured to the vacuum pipe. For the first operation, just prepare the tanker for vacuum operation, turn the handle (G) clockwise (vacuum) of ant-clockwise (pressure) and let the pump run at the estimated turning speed.
  • Page 13 3.2 Lubrication. 3.2.1 Vanes lubrication. While the pump is operating the vanes have to be lubricated. The vanes lubrication oil is filled up through plug E and controlled with the oil lever indicator C (see picture 1). This level has to be controlled each day to be sure that the pump is not running dry. Oil tank capacity allows 4 hours of working time.

  • Page 14: Maintenance

    The vanes have to be controlled after 1000 hours of effective working time and have to be changed it the waste comes up to 10% of the original dimension: KL-18 (600 x 70 x 7,5) mm - 6 Un. VANES CHECKING It is possible to check the wearing of the pump vanes without dismantling the pump thanks the plug W place at the top of the pump body.
  • Page 15 VANES CHANGE: 1.- Take out cooling circuit pipes. 2.- Dismantle cover and gasket. Once you did it, take out the water pump from the cover. Water pump Cover Gasket 3.- Exchange the vanes. 4.- Exchange de gasket. 5.- Mount the cover. 6.- Set the water pump up, fixing rotors intern Groove with the flange.

    3.4. Troubles and solutions. The pump is part of the vacuum tanker. So, check that all the rest of the vacuum circuit is in good condition before checking the pump. It is advised to take apart vacuum pipe and make turn the pump to check if the pump is transferring air before start manipulating the interior of the pump.
