(Scroll down for a full list of materials used in the pump’s construction.)\u003c\/p\u003e \u003cp\u003eEach pump measures 194 x 165 x 121 mm (7.6 x 6.5 x 4.8 inches), and weighs 3 kg (6.6lb). Installation has been made easy with ready-drilled holes for horizontal or vertical mounting. Easy operation has also been considered with a single control for pump output.\u003c\/p\u003e \u003cp\u003e*IP65 (International Protection Rating) equals dust tight and water jet protected.\u003c\/p\u003e \u003ch3\u003e\u003cb\u003eBL3-2 BlackStone Chemical Dosing Pump\u003c\/b\u003e\u003c\/h3\u003e \u003cp\u003eThe BL3-2 BlackStone Chemical Dosing Pump has a flow rate of 2.9 LPH (Litres per hour), rated pressure 8 bar (116 psi), and dosing frequency strokes per minute of 120. Power supply: 220\/240 VAC.\u003c\/p\u003e \u003cp\u003eSimple operation is guaranteed with a single control for pump output. The external flow rate control (potentiometer), on the face of the pump, allows users to adjust the percentage of flow from 0 to 100 per cent thus eliminating concerns over stroke rate or power settings. An LED Indicator lights up each time a stroke begins, allowing the user to keep an eye on the stroke rate from a distance.\u003c\/p\u003e \u003cp\u003eEach pump is supplied with discharge and suction valves.\u003c\/p\u003e \u003ch3\u003eAccessories available:\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eHI-721004 Injection Valve assembly\u003c\/li\u003e \u003cli\u003eHI-721005 Foot valve assembly\u003c\/li\u003e \u003cli\u003eHI-721101 Pump head, O-ring, screws and washer\u003c\/li\u003e \u003cli\u003eHI-721102 Discharge valve assembly\u003c\/li\u003e \u003cli\u003eHI-721103 - Suction valve assembly\u003c\/li\u003e \u003cli\u003eHI-721008 - Ceramic weight (4)\u003c\/li\u003e \u003cli\u003eHI-720011D - Magnet and coil for BL Pumps (230VAC)\u003c\/li\u003e \u003cli\u003eHI-720011U - Magnet and coil for BL pumps (115VAC)\u003c\/li\u003e \u003cli\u003eHI-720025 - Pump body\u003c\/li\u003e \u003cli\u003eHI-720034 - Magnet pump head assembly for BL pumps\u003c\/li\u003e \u003cli\u003eHI-721001 - Complete pump head with valves\u003c\/li\u003e \u003cli\u003eHI-72001 - Tube nut, 5 x 8 mm dia.
