Product Description
ZE range pump is a horizontal, single stage, radially split heavy duty centerline mounted process pump with single flow closed radial impeller. Axial suction branch, vertical radial discharge branch with flanges machined to meet ANSI or DIN standards. Selection is a available with two casing designs, ZE with wall thickness optimized to cover the various pressure ranges. Fully confined gasket between volute casing, casing cover and seal cover. Shaft sealing chamber per ISO21049(API682), specified for the installation of single and double mechanical seals, cartridge design is standard. Connections for flushing, cooling, heating, quench and buffer fluids. Piping as per API plans. Rugged fabricated steel API standard baseplate with drain pan and lifting lugs.
The pumps are designed for the delivery of most fluids found in refinery processes. The application ranges from liquid gases at low temperatures through light and heavy fuels up to gas oil containing solids and distillation residues at the highest temperatures.
ZE pumps can also be employed as turbines for the recovery of energy.

1. Check whether the installation of the pump is reasonable, which has an important impact on the normal operation and service life of the chemical pump, and it needs to be corrected before installation.
2. It is necessary to ensure that the pump cannot be higher than the allowable NPSH when working. The water absorption height of the chemical pump needs to be determined according to the NPSH characteristics of the pump.
3. The suction and discharge pipelines should be additionally provided with brackets, which cannot be supported by the pump body.
4. The place where the pump is installed should be convenient for inspection and maintenance.
5. Installation sequence:
① Place the unit on the foundation with anchor bolts, and place a pair of wedge pads between the base and the foundation for correction.
② Loosen the coupling, place the level gauge on the pump shaft or the base respectively, use the adjustment wedge pad to find the level of the unit, and tighten the anchor bolts to avoid walking.
③ Concrete can be used to pour the anchor bolt hole and the base.
After the concrete is dry, tighten the anchor bolts and recheck the levelness of the pump shaft.
⑤ After connecting the pipeline and determining the rotation direction of the motor, connect the coupling again, review the concentricity of the shaft, measure the difference between the upper, lower, left and right of the outer circle of the coupling not to exceed 0.1mm, and the larger and smaller gaps between the end faces of the two couplings within a week cannot be higher than 0.3mm.
⑥ when the actual operation of the pump 3 hours to 4 hours after the inspection, if there is no bad situation on the installation of qualified.

Causes and Solutions of 1. Pump Not Producing Liquid in Operation
(1) Insufficient liquid in the pump chamber (the gas in the pump is not exhausted). Solution: re add liquid, pump cavity filled with liquid.
(2) Whether the pump operation and steering are correct when the equipment is started. Solution: check the supporting motor running direction.
(3) The speed of the pump is low after starting. Solution: stop to check the motor speed, replace the corresponding speed motor power.
(4) The filter screen at the inlet end is blocked. Solution: check the filter, remove debris, etc.
(5) The suction height is greater than the actual suction height of the pump, and the suction tank is vacuum. Solution: Reduce the suction height and check the pressure of the suction tank.
Causes and solutions of interruption after discharge of 2. pump
(1) Inlet pipeline leaks. Solution: check whether the inlet pipe connection and packing seal leakage.
(2) When filling the pump, the gas at the inlet end is not completely discharged. Solution: Require a refillable pump.
(3) The inlet end is blocked by foreign matter. Solution: stop the pump to deal with foreign matter.
(4) Intake a large amount of gas at the inlet. Solution: Check whether the suction port is vortex and whether the submerged depth is too shallow.
3. pump vibration causes and solutions
(1) the pump axis and the motor axis error is large. Solution: Readjust the position of the two axes.
(2) The suction height is too large, resulting in cavitation. Solution: Reduce the installation height.
(3) there is a phenomenon of mechanical friction. Solution: check where wear, maintenance.
