Avoid high pockets in suction piping, which can trap air. Keep all pipe and fitting connections tight in suction vacuum conditions to prevent air from getting into the pump. 6. ENSURE THE PIPING ARRANGEMENT DOES NOT CAUSE STRAIN ON THE PUMP CASING. Pumps should never support the suction or discharge piping.
A mechanical seal is a device that is used to control leakage between a rotating shaft and a liquid- or gas-filled vessel. Its main responsibility is to control leakage. All seals leak—they have to in order to maintain a fluid film over the entire mechanical seal face. The leakage that comes out the atmospheric side is fairly low; the leakage
Example 12.2 Centrifugal Pump Performance Based on Inlet/Outlet Velocities zWater is pumped at the rate of 1400 gpm through a centrifugal pump operating at a speed of 1750 rpm. The impeller has a uniform blade length, b, of 2 in. with r 1 = 1.9 in. and r 2 = 7.0 in., and the exit blade angle is β=23º . Assume ideal flow conditions and that the

Use Table 3 to reduce the published pipe stiffness of PVC pipe and conduit if the operating temperature exceeds 73°F. For appliions below 73°F, use the published pipe stiffness since they will be conservative. Table 3 is also applicable as a temperature correction chart for the modulus of elasticity (E) for PVC pipe and conduit.

21/3/2022· Suitable materials for the vent and condensate pipes include PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), and ABS (acrylonitrile-butadiene-styrene) plastic pipe, depending on the furnace’s specified exhaust gas temperature. These different plastics have different maximum heat service temperatures: PVC has the lowest rating
21/11/2019· NFPA 20 permits a maximum of three pumps to operate in series (NFPA 20-2013, Section 188.8.131.52). Fire pumps cannot operate in parallel because the discharge check valve is forced closed when the pressure on the outlet side of …

API 610 provides a classifiion for various types of centrifugal pumps. The API 610 pumps are primarily divided in three groups: OH, BB and VS. OH–Overhung pumps– The impellers of these pumps protrude from the bearings.The support has to take care of all forces, e.g. the overhung mass and the rotor dynamic and hydraulic forces.

14/3/2014· For example, if you have a 40,000-square-foot building that is all ordinary group 1, the calculation would be 1,500 x 0.15 (density) = 225 + 250 (hose demand) = 475 gpm total for the fire pump. If the structure has multiple hazards, the hazard with the highest gpm calculation dictates the pump size.
