The user is responsible for the verification of the ambient conditions where the pump will be stored or installed. - STANDART POMPA does not guarantee repairs or alterations done by user or other unauthorized personnel. The use of original spare parts and accessories authorized by manufacturer will ensure safety.
A2- Applications SNL series pumps are suitable for clean or slightly contaminated (max. 20 mg/dm³) liquids with low viscosities and temperatures up to 110 º C. The main application areas, among others, are Water supply systems, Warm water heating, chilled and cooling water systems.
Carefully remove the packaging material and check that pump and accessories (if any) are free from any markings, stretches and damages, which may have occurred during transportation. In the event of damage report this immediately to STANDART POMPA’s service department and to the transport company.
B3- Storage If the pump is not to be installed and operated soon after arrival, store the pump in a clean, dry and frost- free place with moderate changes in ambient temperature. To prevent the pump from moisture, dust, dirt and foreign materials suitable steps should be taken. The pump shaft should be revolved periodically (e.g.
C4- Connecting The Piping C4.1- General Never use the pump as an anchorage point or as a carrier for the piping. ATTENTION The pipes should be supported very near the pump (Fig. 3). It must be checked that any weight, stress or strains on the piping system should not be transmitted to the pump.
C4.3- Discharge piping (Fig. 4) A control valve should be installed in the discharge pipe, as close to the pump as possible, to regulate the required flow and head. If the total head of the pump exceeds 10 meters or if discharge line is of appreciable length a non return valve should be installed between the pump and isolating valve on the discharge line to protect the pump against water hammer and reverse flow on shut down.
C5.6- Electrical connections The electrical motors have to be built in accordance with EN 60034-1. Enclosures of electrical motors and control systems on the pump unit shall as a minimum give protection in accordance with EN 60529 IP22. But in determining the degree of protection of enclosures of electrical motors and control systems on the pump unit the operating and environmental conditions must be taken into consideration.
C5.7- Final check After completion all the above process rotate the pump rotor several times by hand. Make sure rotor rotates easily. Fix the safety guards back in places. Do not operate the pump before doing so. This is a necessity for security and job safety.
D3- Shut Down The Pump Slowly close the shut-off valve in the discharge line. You may shut down the pump without closing the shut-off valve if there is a device for water hammer protection on the discharge line or the water hammer is not a considerable level. Switch off the driver.
F2- Reassembly Reassembly proceeds in reverse sequence to disassembly as described in section F1. You may find the attached drawings useful (see sectional drawing in section M). Coat the seats and screw connections with graphite, silicon or similar slippery substance before reassembly. If you can not find any of the above you may use oil instead (except the pumps for drinking water).
NOTE : See section L for pump dimension group G- SPARE PARTS STANDART POMPA guarantees to supply the spare parts for SNL type pumps for 10 years. You can provide any spare parts easily. Lets us know the following details on the name-plate, when you order spare parts.
