Mechanical : 3. Equivalent metric dimensions, fasteners, and flanges may he substituted as mutually agtced between the purchaser and the vender. Conflicting Requirements In case of conflict between this standard and the inquiry for order, the information included in the order shall govern, 1.

The power end is a mechanism that traas- mits energy from a rotating shaft to pistons or plungers by means of crankshaft, crossheads, and connecting rods. Power is directly vansmitted tothe liquid end by the action of the motive fluid on the drive end.

A irect-acting pump may use steam, ait, or gas as the motive fuid. Piston or plunger load is the force acting on one plunger cot piston during any portion of the pumping cycle. Minimum allowable speed in revolutions per minute is the lowest speed at which the manufacturer's design will permit continuous operation Rated discharge pressure is the discharge pressure of the pump at rated capacity, speed, suction pressure, specific gravity, and viscosity.

Rated capacity of a reciprocating pump is the total volume of fluid actually delivered per unit of time at the stated operating conditions. Rated capacity includes both liquid and any dissolved or entcained gases. NPSHA for 1 reciprocating pump is normally expressed in pounds per square inch.

Seal-welded connections shall be made up without thread labricants or compounds. No undercutting shall be permited, 3. He and L-inch pipe. The make and model of fittings shall be subject 0 approval by the purchaser. Close nipples aze not secaptable. Horizoctal runs shall slope continuously, 44 inch per foot minimem, toward the reservoir. The vendor shall advise the purchaser on the basis of his knowledge and experience of any hazards in the use, sizing, arrange- ment, oF the like, that may cesult in damage to the equipment 3.

Three basic types of pulsation suppression devices are given in Items 1 through 3 below. Consideration should be given to the following factors: 1 pump horse: power, 2 discharge and suction pressures, 3 number of cylinders per pump, 4 number of pumps operating parallel and the possibility of pulsation interaction, and 5 critical nature of the installation. Additional information on pulsation suppression devices may be obtained from API Standard The purchaser shall furnish such devices unless otherwise agreed upon.

It shall be the responsibility of the vendor to notify subvendors of the purchaser's inspection require- ments, 4. Purchase specification forall items on bills of material 3.

Running tect data to verify thet the requirements of the specification are being met. Results of quality assurance tests 4. When ultrasonic inspection is specified, procederes and acceptance criteria shall be rmotually agreed upon. For cach type of defect, the degree of severity shall not exceed the limits inthe following table: Tye Degree 1 L u 2 tm 2 wv 1 wt t Regardless of these generalized limits, it shall be the vendor's responsibility to review the design limits of all castings in the event more stringent requirements are specified.

Where defects exceed the limits imposed above, they shall be cleaned out to meet the quality standards referenced above as determined by additional magaetic- particle inspection, prior to repair welding 4.

Witnessed mechanical test or running performance test 4. Unwitnessed or witnessed NPSH test in accordance with 4. Dismaniling, inspection, and reassembly of liquid end after running test if not needed to satisfy the requirement 0f 4. Liquid and ges ends may be segmentally tested at appropriate section pressire, When suction and discharge test pressures vary, these differences shall be noted on the datasheets in the proposal.

The pressure tus obtained shall then be the minimum pressure at which the hydcostaic test shall be performed, The data sheet shall list actual hydrostatic test pressures. Large and heavy castings or forgings may require 1 longer testing period to be agreed upon by the purchases and the vendor. Seepage past internal closures required for segmented liquid ot gas end testing and operation of the test pump to maintain pressure will be accepted.

However, the recorded data, and final report may include information on the complete unit, including driver and ausiliary equipment. The preparation shall be suitable for 1 period of 6 months of outdoor storage from the time of shipment, such that disassembly is not required, except for inspestion of beatings and seals, prior to operation.

If storage is contemplated for longer periods, the purchaser shall consult with the vendor regarding the recommended procedures to be followed, 4. Preparation for shipment shall not be made ntl all testing and inspection of the equipment has been accomplished and the equipment has been approved by the purchaser.

Minimum preparation shall include that specified in 4. In no ease shall nonmetallic plugs such as plastic be used. All material shipped separately shall be identified with securely af- fixed, corrosion-resistant metal tags indicating the item and serial number for which itis intended. Field labor charges, if any, shall be subject to negotiation between the vendor and the purchaser 5. The vendor informa- tion data sheet Appendix C shall be included, showing the schedule of transmission of drawings and data, 1.

Copies of purchaser's data sheet s with complete vendot's information entered thereon. A specific statement that the system aad all compo- nents are in strict accordance with the purchaser's speci cations. If they are not in strict accordance with the specifications, the vendor shail include a specific list detailing and explaining every deviation.

Deviations may include alternative designs oc systems equivalent 10 and guaranteed for the specific duties. An explicit statement of any deviations from the specified guarantee and warranty see Section 5.

A statement of the fixed number of weeks to effect shipment after receipt of the order or after release for manufacture, whichever applies. A list of spare parts recommended for normal maintc- nance purposes. The purchaser shall specify any special requirements for long-term storage.

Price details fr spare parts are not required unless specifically requested by the purchaser. An itemized list of the special tools included in the offering.
