High Pressure Portable Water Pump For Car Wash
PRODUCT DESCRIPTION
INDUSTRIAL PUMP DP SERIES
Installation and Operation Manual
CAUTION: "Intermittent Duty" is defined as; operated and / or frequently started within a period of time that would cauce the motor to reach its maximum themal limits. Once the maximum themal limit is obtained, the motor must be allowed to return to ambient temperature before resuming operation.
CAUTION: DO NOT use to pump flammable liquids. Never operate the pump in an explosive environment. Arcing from the morto brushes,switch or excessive heat from an improperly cycled motor may cause an explosion.
CAUSTION: DO NOT assume fluid compatibility.If fluid is improperly matched to the pumps elastomers, a leak may occur. Pumps are used to transfer hazardous or hot (max.temperature 76 degree,Viton only) chemicals must be in vented area to guard againest the possibility of inquiry due to harmful or explosive liquid / vapors.
CAUTION: DO NOT operate the pump at pressure which cause the motor to exceed the amperes rating indicated on the name plate. Various pump models are equipped with themal breakers to interrupt operation due to excessive heat.Once the temperature of the motor within proper limits it will automatically reset, and the pump will start operation without warming.
CAUTION: To prevent electrical shock, disconnect power before initiating any work. In the case of pump failure, the motor housing and / or the pumped fluid may carry high voltage to components normally considered safe.
PRESSURE SWITCH OPERATION (if Equipped)
The pressure switch reacts to outlet pressure, and interrupts power at the preset shut-off pressure indicated on the pump lable.When outlet pressure drops below a predetermined limit(typically 15-20psi, 1-1.4bar) less than shut- off pressure. The switch will close and the pump operates until the shut-off( high) pressure is achieved. The shut-off pressure is set to factory calibrated standards.
CAUTION: Improper adjustment of the pressure switch setting, may cause severe overload or premature failure. Failures due to improper adjustment of the pressure switch setting will not be covered under the limited warranty.
If the plumbing is restrictive or the flow rate is very low, the pump may re-pressurize the outlet faster than the fluid is being released, causing rapid cycling(ON/OFF) within 2 sec.) If the pump is subjected to rapid cycling during normal operation, or for infrequent periods, damage may occur. Applucations which exhibit rapid cycling should have restrictions in the outled minimized. If not feasible consider a accumulator or a "bypass" model pump.
TECHNICAL DATA OF HIGH PRESSURE PUMP
TROUBLE SHOOTING
PUMP WILL NOT START
- Fuse or breaker
- For correct voltage(±10%) and electrical connections
- Pressure switch operation and corect voltage at switch or motor wires (as equipped)
- Rectifer or motor for open or grounded circuit
- For locked drive assembly
WILL NOT PRIME (No discharge/ motor runs)
- Out of product
- Strainer for debris
- Inlet tubing/plumbing; severely restricted(kinked)
- Debris in pump inlet/outled values
- Proper voltage with the pump operationg(±10%)
- Pump housing for cracks
LEAKS FROM PUMP HEAD OR SWITCH
- For loose screws at switch or pump head
- Switch diaphragm reptured or pinched
- For punctured diaphragm if fluid is present at bottom drain holes.
Pump WILL NOT SHUT-OFF (Pressure switch equip.)
- Output line closed and no leaks
- For air trapped in outlet line or pump head
- For correct voltage to pump(±10%)
- Inlet/Outlet valves for debris or swelling
- For loose drive assembly or pump head screws
- Pressure switch operation/adjustment incorrect refer to S/B# 1031 for differetial and pressure adjustment procedure
NOISY/ROUGH OPERATION:
- Mounting feet that are compressed to tight
- For loose pump head or drive screws
- Does the mounting surface multiply noise(flexible)
- Is the pump plumber with rigid pipe causing noise to transmit
