MS-HC Hastelloy C
Pump Tube Lengths - 27",
Mechanical Sealed design for sticky and abrasive liquids
The sealed Lutz pump tube is designed that it can handle light abrasives, liquids that harden, liquids that crystallize or which are sticky. Clear liquids can be best handled with the MSL sealless design. It is suitable for pumping slightly viscous, aggressive and non-aggressive liquids. The pump tube is ideal for transfer out of drums or containers. The pump tube is non-lubricated and will not contamination of the liquids pumped. It is not suitable for flammable liquids except when constructed of stainless steel.
Examples of liquids pumped
Acids, Caustics, Plating Solutions, Phosphates, Sulfates, Nitrates, Chlorates, Paints and Inks, Hydroxides, Sulfites.
Lutz pump tubes are immersible centrifugal pumps. The impeller or rotor pumps liquid up the pump tube and discharged through the outlet near the top of the pump. The drive shaft (high nickel or stainless steel) of this pump tube is sealed with a Viton ceramic mechanical seal. Two types of pumping elements are available: axial-flow = R (rotor) and radial-flow = L (impeller). The rotor is ideal for most transfer application -- it produces the most flow rate (30 - 45 GPM) at moderate pressures (10-18 PSI). The impeller is used when higher pressure (30-35 PSI) is desired. Conversion in the field from rotor to impeller is quite simple. The actual pump flow / pressure is dependent upon the motor selected as is the maximum viscosity and solution specific gravity. Generally, rotors are suitable for up to 900 cps and 1.8 Sp. Gr. -- impellers up to 1150 cps and 2.0 Sp. Gr. For best assurance of desired results, please provide us with details for final selection.
A handwheel is used to attach the pump tube to the motor -- it is simply turned to tighten. The hand wheel also serves as a protection device in the event of the pump being dropped and is used as a hand support during transfer or when the pump is hung in the wall bracket.
Accessories supplied with poly pump tube include: wall bracket, 8 feet 3/4" ID PVC tubing, hose clamps and barrel adapter. Stainless and Hastelloy pumps include: wall hanger, 10' bonding wire, (2) 6' grounding wire. Aluminum pump includes wall hanger. Optional quick disconnect fittings, larger tubing, and other accessories are available for all models.
* Optional Rulon bushing should be used for Nitric Acid
