Smith Precision 泵|连轴器|过滤器Smith Precision Products Company (Smith Pumps) has been designing and manufacturing positive displacement pumps since 1938. Specializing in liquefied gas transfer, the product line incorporates many model types with accessory items such as bypass relief valves, flexible drive couplings, and Y-type strainers.In 1949, the company started to produce fertilizer injectors. Today's product line incorporates a complete line of water-powered injectors well known for accuracy, dependability, and superior quality.Smith Precision Products Company maintains long-standing relationships with its distributors worldwide and is committed to providing superior products and meaningful customer service. The company continues to be managed by third generation Smith family members that are intimately involved in the industry, helping to ensure an unequalled continuity of company policies and procedures, product design and development, quality systems implementation, and product field performance.  Each D-series pump comes complete with a back to tank bypass valve and built-in strainer. Without disturbing the piping, the gear set and strainer screen can be serviced. Likewise, should the mechanical shaft seal assembly require replacement, the gear set does not have to be removed from the pump. Each D-series pump uses a BUILT-IN bypass valve cartridge set at 90 psid. Pump bypass must be piped back to the supply tank. Designed for direct motor mount to 56C-frame electric motor. Foot mount available. PUMP SPECIFICATIONSPUMPS ONLYAVERAGE DELIVERY RATE GPMINTERNAL BYPASS RELIEF VALVE SETTINGMAXIMUM DIFFERENTIAL PRESSUREINLET/OUTLET SIZE: FEMALE THREADEDMOTORPUMP ROTATION AS LOOKING AT PUMP SHAFT-ENDMODEL40 PSID, 3600 RPM75 PSID, 3600 RPMPSIPSIINCHESH.P.DW-1Z8-1/27901253/41CWDW-HZ13-1/2129012511-1/2CW  The model MC-1044 pump incorporates the balanced 3-gear design to maximize efficiency and minimize slippage. The MC-1044 is reversible with proper consideration of inlet and outlet ports. The MC-1044 can fill up to three 100 lb. cylinders in 4 minutes using a manifold arrangement. As with all Smith pumps, no periodic maintenance or lubrication is required. Since the pump loading is balanced and no heavy rotor is utilized, the mechanical shaft seal ball bearing sees minimal work. It is sealed for life and does not require periodic greasing. PUMP SPECIFICATIONSPUMPS ONLYAVERAGE DELIVERY RATE GPMMAXIMUM DIFFERENTIAL PRESSUREINLET/OUTLET SIZE: FEMALE THREADEDMOTORPUMP ROTATION AS LOOKING AT PUMP SHAFT-ENDMODEL40 PSID, 1800 RPM75 PSID, 1800 RPMPSIINCHESH.P.MC-104417141251-1/21-1/2 H.P.

Is recommended as a heavy duty bulk plant pump with a capacity up to 100 GPM. Inlet and outlet ports are conveniently located on the sides of the pump to minimize restrictions caused by fittings such as elbows. MC-3H model delivers the same capacity as the MC-3 but at 1500 RPM.

The proportion of water to chemical solution remains the same, regardless of changes in water pressure. The solution is injected in an accurate, controlled proportion as water passes through the machine. The proportion also remains the same regardless of the amount of water that flows through, within wide limits. The MEASUREMIX can never inject more solution than the set proportion allows, no matter what goes wrong. This important feature prevents plant "burning" and expensive losses under any condition. Your plants are safe with a Smith MEASUREMIX.Simplicity of OperationThe Smith MEASUREMIX has a precision-built water motor connected internally to a piston-type injector pump. The MEASUREMIX operates on water power and requires no electric motor or gasoline engine. The water passing through the water motor provides the power to run the injector pump. The water motor actuallymetersthe water running through. For every revolution of the water motor, there is one stroke of the injector pump. By this simple principle, the proportion of water to fertilizer-solution is always accurately maintained.Variety of usesThe Smith MEASUREMIX is built to dispense all kinds of liquid chemicals. The machines are built of the finest materials known. The water motors are built of bronze and stainless steel. The injector pistons are built of stainless steel on all models, and valves and fittings in the injector system are stainless steel on standard models. A great variety of liquid solutions may be used, as has been proven by years of service in many localities.AccuracyThe Smith MEASUREMIX is accurate within 95 to 98 percent. At a standard ratio of 1 to 100 for example, this accuracy ensures that the fertilizer solution will always be maintained between 1 part in 95 parts of water and 1 part in 105 parts of water. Frequently, accuracy is maintained between 1 part in 98 and 102 parts of water.Proper Choice of liquid fertilizerWe strongly advise that your choice of chemicals be based on advice of soil analysis experts. Advice from these persons who can analyze your soil regularly will bring you the greatest success and will cost the least in the long run. If their advice to you is to use chemicals or mixes that can be applied in a liquid form, the Smith MEASUREMIX is the injector to use, as it was designed to meet the practical demands of scientific soil control.Economy and SavingsThe Smith MEASUREMIX is designed to provide economy of operation. You save cost of labor and you save time when you fertilize while you water. You save fertilizer cost, as liquid fertilizer usually costs less than solid fertilizer. Finally, with a controlled fertilizer program, your plants grow better, yielding more profit to you.  Smith differential bypass valves offer the ultimate in simplicity and utilize superior materials for longest life.The Smith bypass valve is CHATTERFREE due to the unique guide-piston design. The guide -piston is manufactured from STAINLESS STEEL for tough applications and to minimize corrosion damage. The spring is also STAINLESS STEEL and is designed for an infinite number of cycles.All Smith bypass valves incorporate a unique flow plate to evenly dissipate flow when the valve opens. This eliminates chatter and minimizes overpressure even at higher flow rates. The valve is designed for continuous flow applications as well and can be used to meter flow if desired.Underwriters Laboratories requires that all pumps except models DW-1Z, EG-1Z, EC-HZ, MC-1, and GC-1 be fitted with external bypass relief valves set no higher than 125 PSID.VALVE SELECTIONMODEL SIZE PUMP RECOMMENDED FLOW(GPM)WW-1201/2 x 1/2DW-1Z, EG-1Z, MC-1, GC-15-10WW-3403/4 x 3/4DW-HZ, EC-HZ10-15WW-1001 x 1MC-1044, MC-1044H, TC-1044H20-35WW-1141-1/4 x 1-1/4MC-2, MCAT-2, MC-2H, TC-235-50WW-1121-1/2 x 1-1/2MC-3, MCAT-3, MC-3H, TC-350-100WW-2002 x 2MC-4, MC-4H100-150WW-2122-1/2 x 2-1/2MC-5, MC-5H150-250
