CHM GmbH Centrifugal pump stainless steel 1500 watt with pressure switch (sensor technology and LCD display) latest generation. Attention: This pump is only suitable if a check valve or foot valve is present at the bottom (e.g. for a well/cistern). We do not recommend the check valve directly in front of the pump and advise against purchase. Description: Pump starts and stops automatically, depending on the desired setting. Very smooth running 68 db, high pressure build up with large flow rate as well as an integrated hot running protection in the motor winding characterise this pump. Thermal protection: integrated overheating protection in the motor winding. Technical data centrifugal pump: 1.5 KW 230 V / 50 Hz Protection class: IP 44 discharge height: 85 m max. Pressure: 8.5 bar. Max. Flow rate: 8400 L/h - 140 L/min. Max. Suction height: 8 m at 1 inch. Robust and rust-proof stainless steel shaft. Multi-stage centrifugal pump. 8 x stainless steel paddle wheels covered with plastic for good smoothness. Max. Water temperature: 60 °C connection suction and pressure side: 1 inch internal thread The pump has 2 mounts at the bottom, suitable for mounting on a pressure boiler. Cable length: 30 cm with plug L W H: 55 x 15 x 18 cm. Noise level: 68 dB. ! Garden irrigation > > max. 4 sprinklers can be connected. Please note that we do not recommend PE pipes as suction lines. The cable or consumer on the pressure side should have at least 1 inch. Otherwise, you also need a pressure expansion tank. ! Important! The pump should be placed near the fountain hole to ensure the max. suction height. Equip the intake line with a check valve to ensure that the water column is maintained. If the check valve is installed in front of the pump and not as a foot valve, then you must also form a water column under the check valve. The water column must be resistant, as the pump cannot suck air which is in a suction line. Please fill the pump and suction line with water before use, otherwise there is a risk of dry running. The suction line should have a diameter of 1 inch - 1 1/4 inch and not be smaller or larger. Otherwise, the pump cannot provide the appropriate power or pressure. If you are not sure of these requirements on site, please buy our Jet pump in our shop. This pump can suck in air, even if it does not have quite as much capacity for it. Technical data pump control: input voltage: 220-240 volts maximum operating pressure: 10 bar working and switching capacity up to 2.2 KW frequency: 50-60 Hz time adjustable for automatic restart. Display of the current pressure in the display during operation. Switch off pressure adjustable: 0.5 - 9.8 bar power on pressure adjustable percentage 30-80% of set off pressure = 0.3-7.9 bar (factory setting 5.0 bar) maximum temperature: 60 ? Current consumption: 10 A, protection class: IP54, dry running protection: switches the pump out of check valve in case of lack of water: prevents pressure impact effects connection: 2 x 1 inch external thread distance between both water flows outside 170 mm. Warning: installation position only possible vertically, so that connections are vertical up/down. The cable or consumer on the pressure side should have at least 1 inch. Cable length plug 80 cm and coupling 50 cm. Dimensions: 25 x 17 x 17 cm. Weight: 1.6 kg. Box contents: centrifugal pump 1.5 KW and pump control adjustable in original box with BA in German/English
