The shaft sealing package is made up of oil-filled asbestos packing,gland,seal cage and stuffing box on the pump casing.Its function is to prevent air from getting into the pump and too more water from coming out of the pump along the shaft. The shaft sleeve is used to prevent the shaft from rubbing with the packing stuff.The sleeve should be replaced in time when it wears out. The pump shaft is supported by single-row annular contact ball bearings.The bearings shall be lubriccated with oil which should be kept between the lines on the oil level indicator,or with grease which has already been put into the bearing case during assembling,it can be added after the front and rear end coves are dismounted,or by oil holder. The screwed hole on the top of pump casing is used for pouring prime water into the pump or connecting,with a vacuum pump to evacuate air and draw up water.Application Range: Main performance range of HWandHBCpumps: Capacity:130m³/h~1200m³/h Head:3.5m~15mThe Direction of Rotation: As viewed from the suction side of the pump,the rotation of the impeller is anti-clockwise.ModelSpeedFlowHeadEfficiencyShaftPowerMotorPowerCavitationNetWeightrpmm3/hl/sm%(kW)(HP/kW)mkg100HW-8S(4HBC-35)290068199.6802.244/343090258108306150HW-5S(6HBC-35)1450137386.180.535/4365180505216603.71850175491080.56.312/7.53.5230648.2276766.1150HW-8S(6HBC-25)1450137388.7824.788/5.52.760180508216606.8150HW-12S(6HBC-35T)29001373815.3827.4712/116601805012.5216609.7200HW-4S(8HBC-40)1060300835814.68/5.543409544201173200HW-5S(8HB-50)1160250696.781.56.0112/7.5411036010054401224200HW-5(8HB-50)1450240676.881.56.0112/7.5436010054451243.9200HW-8S(8HBC-35)1360250708.5827.912/104340957.14051125.31450270759.6829.611/15436010084321206200HW-12S(8HBC-25)14502707513.583.514.6825/18.5410536010012.543212010.8250HW-4S(10HBC-40)980400111482.56.312/7.541654501254.24801333.511104501257848.811/15454015056501804.1250HW-5(10HBC-50)11804401226.8819.111/15416554015056601834250HW-7S(10HBC-30)870355986.5837.412/1144001115.5450125598040011188310.520/15445012575001396.3250HW-8S(10HBC-45)11004601289.184.513.925/18.5417054015086601835250HW-8(10HBC-45)11804501259841425/18.5417054015086701864.9250HW-12S(10HBC-25)118050013914.68424.440/30416560016712.57101979.8300HW-4S(12HBC-50)7806501805.483.59.411/15471019748102253300HW-5S(12HB-45)8706601835.68412.825/18.5479222059002504300HW-5(12HBC-45)9806501805.58412.825/18.5419579222058902473.9300HW-7S(12HBC-40)7305081414.5847.312/1145851633.97232012.898068018988417.730/22478021679102525300HW-8S(12HBC-40T)9706601839.18520.330/22420079222089002506.5300HW-12(12HBC-25)97067018614.48531.850/37420079222012.591025310.1350HW-4S(14HBC-50)9809002505.18516.630/224.533010002784.311803283.5350HW-8S(14HBC-40)7306701865.285.510.520/154.53307452074.48192283.79809002509.485.525.540/304.51000278811003066.7400HW-7S(16HBC-40)73010803007.88628.140/30555512603506.813683806.2980145040314.18666100/755.5169247012.3183651011.2400HW-10S(16HBC-30)730109830511.58644.560/55556014003901017204787.55980147041020.786106165/1105.5188052018230064013.6500HW-6S(20HBC-40)58016904697.68638.960/555.579019805506.221806065.37302127591128677.3120/95624926929.827447628.4650HW-7S(26HBC-40)45030608507.49068120/905.5180034009446.53960110055904014111512.790152220/18064457123811.2519314428.6650HW-10S(26HBC-30)490265873810.98998.6150/1155.5180033229239.7415311548.6590320088915.889171250/1805.540001111145000138910.4
