Bareshaft Pump COMPONENT IDENTIFICATION Before operating the unit it is necessary to fully understand each component and how it functions. Following is a brief description of the unit’s main components. Figure 1: Bareshaft Pump. Pump Manifold Drain Valve The UNx pump uses the power from the engine The manifold drain valve allows the manifold to be to pressurize the source water into high pressure flushed of contaminants prior to pump usage.
If a rupture disc should burst, there is no way to build pressure until the disc is Regulator Valve (Not Shown) replaced. Use only genuine Jetstream rupture discs For shut-in systems (where no low pressure water properly rated for the intended operating pressure.
Bareshaft Pump Bypass Valve Discharge Fitting Supply Couplings Figure 3: Pump Components (Continued). Supply Couplings The supply couplings provide a quick method for attaching the supply hose to the manifold. Secondary Filter (40K Units) A secondary filter (Figure 4) is mounted on top of the pump for use when operating at “40K”.
Models Positive displacement pumps create pulsation in the high pressure discharge line. For this reason, The Jetstream UNx bareshaft pump is available in it is extremely important to utilize flexible hoses three horsepower ranges and three pressure ranges (ie rubber, thermoplastic) in lieu of rigid piping to –...
Bareshaft Pump Jetstream 6000 Bareshaft Pump Installation Guidelines All of the previous requirements are the same for 6000 except as noted below: The 6000 powerend is internally geared and requires inline drive with flexible coupling ***. It is available in four different gear ratios to support diesel engine or electric motor input speeds.
*** Driver selection and coupling selection requires engineering analysis of torsional loads and vibra- tions (TVA). Jetstream can supply the mass- elastic data for the pump but it is customer’s responsibil- ity to perform TVA of the system. Coupling failure, engine damage, and powerend damage can result from incorrect coupling selection.
OPERATION Recommended Equipment Hose and Water Supply Requirements Jetstream equips the waterblast units with the com- ponents they recommend for safe operation. Those – The water supply hose inside diameter must components include: be large enough to supply 150% of the unit’s •...
Operation Manual Start-up Preparation 1. Inspect the filter bags. Inspect the secondary filter cartridge if operating at 40K. 2. Check the tightness of the gland nuts on each stuffing box. 3. Inspect all equipment. Ensure that every piece of equipment in the pressure circuit is properly rated for the intended operating pressure.
Bareshaft Pump 13. The nozzles can now be installed on the dis- Flushing the System charge device(s). 14. Before waterblasting, adjust the lubrication line With the engine at idle, warming to operating tem- needle valves, if equipped. Refer to “Checknig perature, flush the system of any debris.
Operation Manual Checking the Water Lubrica- tion System 1. Lift the rod box cover to view the water lubrica- tion system. Lubrication Line Stuffing Box WARNING There are moving parts inside the rod box that can cause serious injury. Use extreme cau- tion.
Bareshaft Pump Raising System Pressure ATTENTION Always blast with the bypass valve fully WARNING closed. This will ensure the most efficient oper- ation with all water being utilized. If less water volume is required, reduce the engine rpm to Before building pressure, contain the high pressure discharge hose.
Operation Manual Breaking in New Packing ATTENTION This procedure is only applicable for 15K and 20K molded packing. It is not required for plastic packing. New packing must be broken in to prevent damage and ensure optimal performance. Break-in should occur in three to four pressure increases over a 5 minute period.
Bareshaft Pump Monitoring Weep Holes Weep holes are manufactured into the manifold to alert the operator when seals have failed. If a seal fails, the Face Seal weep hole water will leak from its associated leakage hole. There are two types of weep holes, the high pressure face seal weep holes that are rectangular slots (Figure Uni-valve 11) and the low pressure uni-valve seal weep holes...
Bareshaft Pump MAINTENANCE 100 Hours Daily Initial Power End Oil Change - After the first Check Power End Oil Level - Add oil as 100 hours of operation on a new unit, change necessary. Refer to “Checking Power End Oil the power end oil.
Operation Manual Winterizing The Pump Severe damage can result if the waterblast unit is not protected from freezing conditions. The stuffing boxes hold water that can freeze, causing damage to the stuffing boxes, uni-valves, plungers and man- Funnel ifold. To prevent freezing, drain the water from all Assembly hoses, charge pump and tanks, and add anti-freeze to the stuffing boxes.
Jetstream does not have a compatible fluids list at together with other properties of the water, lead to this time. The use of any fluids other than water void premature failure (such as cracking) of pump com- warranty.
Operation Manual Secondary Filter (40k Operation Only) Pressure Switch The secondary filter, or polishing filter, is used for 40K operation only. When operating at 40K, monitor the filter pressure gauge (Figure 17) for an indication of filter condition. During normal operation, the pressure gauge should be within the 30 to 40 psi (2 to 2.75 bar) range.
7 to 10 psi (0.48 to 0.69 bar). If the switch doesn’t close within the 7 to 10 psi (0.48 to 0.69 bar) range, it may need to be adjusted. Contact Jetstream for switch adjustment instructions. Uni-Valve Life The uni-valve seats can be damaged by dirty water.
WARNING When switching to higher operating pressures, it Bypass Hose is necessary that all equipment be properly pres- sure rated. Refer to the Jetstream Safety Manual Supply Coupling for specific guidelines for hoses, fittings, etc. Converting a Pump Use the following procedure to convert a pump to a different pressure.
