PW type pharmaceutical pump / chemical petroleum pump 960~2950 r/min


Product Description


PW, PWF horizontal sewage pump is a single stage, single suction, cantilever centrifugal sewage pump. The pump inlet is axially horizontal and the pump outlet can be installed horizontally or vertically as required. Mainly by the pump cover, pump shell, impeller, shaft seal, shaft, and bracket and other components. The shaft seal is in the form of a novel double-ended mechanical seal construction. The pump and the motor are mounted on a common chassis and are driven directly by the motor through a flexible coupling. The pump has high efficiency, energy saving significantly, smooth operation, reliable performance, easy maintenance and so on.


PW type horizontal sewage pump structure Description:

  • This type of sewage pump is mainly composed of pump cover (1), pump body (2), impeller (3), shaft (15), shaft seal (4), bearing box (11) See Figure 1: Structure chart
  • The pump outlet is vertically upward and can be mounted horizontally. The pump is driven directly by the elastic coupling (it is also possible to switch to belt drive as needed).
  • There are only two curved blades in the impeller, so the flow channel is clear and can be used by the general suspension of particles.
  • The impeller the back of four pairs of leaves to balance the axial thrust, the manufacture of impeller after static balance test experience.
  • The direction of rotation of the pump is clockwise from the drive end.
  • Bearing box bearing with thin oil lubrication, oil level by the oil level instructions, the oil level should be in the normal oil level line.
  • The pump shaft seal with oil seal? Seal, good sealing performance, easy to replace.
  • The seal ring is made of cast iron and is fixed to the pump cover and can be replaced with spare parts after wear.
  • The gap between the pump cover and the impeller inlet end, the seal ring and the impeller assembly gap T.

PW horizontal sewage pump Scope:

  1. PW horizontal sewage pump can transport sewage, containing suspended solids, long fiber material and domestic wastewater. The pump body is of high quality cast iron material, the medium temperature does not exceed 100 ℃.
  2. PWF stainless steel sewage pump can be transported with acidic, alkaline or other corrosive sewage, widely used in chemical, petroleum, light industry, food, pharmaceutical, brewing, environmental protection and sewage treatment industries. The pump body and the overcurrent part are made of 304 stainless steel, the medium temperature is not higher than 100 ℃.

PW type horizontal sewage pump start, stop and run:


1. start

  • Check whether the bearing tank has been refueled, the oil level is normal oil level line.
  • Check that the direction of rotation of the motor is the same as the direction of rotation of the pump.
  • Close the outlet valve and pressure gauge cocks, while the upper part of the pump screw hole, to the pump suction pipe irrigation.
  • Start the motor and open the pressure gauge cock.
  • to be the normal speed of the pump to work, the pressure gauge shows the corresponding pressure, open the vacuum table cocks and gradually open the drain line on the valve to the needs of so far.stop

2. Stop

  • Slowly close the outlet pipe valve, and then cut off the power.
  • In case of frozen season, after the shutdown, open the lower part of the pump body of the four plugs, venting water, so as not to crack.
  • If the long term do not, then the parts should be opened to wipe, and in the sliding surface coated with anti-rust oil, proper preservation.

3. Running

  • During the operation of the pump, we must pay attention to observe the instrument, bearing heat, filler leakage and pump vibration, noise, etc. are normal, such as abnormalities should be promptly treated.
  • bearing the maximum temperature shall not exceed 75 ℃.
  • bearing oil should be maintained in the normal oil level line, not too high or too low, too low should be timely refueling.
  • seal ring and impeller with the gap, greater than the following specified value should be replaced when the new seal ring.

When the diameter of the suction nozzle is less than or equal to 100mm, the total clearance in the diameter direction is ≥1.5mm

When the diameter of the suction port is> 100mm, the total diameter of the diameter is ≥2mm


PW type horizontal sewage pump assembly and disassembly:


First check the other parts, the existence of the impact of assembly defects, and then scrub clean before assembly.

  1. ready to pad, silk plug, pipe block and were installed on the corresponding parts.
  2. the seal ring, shaft seal box, oil and oil hole cover, felt store were loaded into the pump cover, bearing body, bearing box, bearing cover.
  3. the first bearing into the shaft at both ends, together into the bearing box, and then loaded bearing gland.
  4. followed by bearing body, bearing (4PW no) oil seal and washers, impeller, gasket and impeller nut and tighten, and then install the pump and pump cover. Disassembly and assembly must be reversed.

PW type horizontal sewage pump Note:

  1. pump inlet and outlet pipes should be set up, not to support the pump:
  2. outlet water piping should be installed gate valve;

In the pump inlet pipe, inlet should be installed general trash rack, to prevent the larger stones and other objects into the pump to break the leaves.
