Pumps. Well pumps used on the project shall be vertical turbine pumps operating at a maximum speed of 1800 rpm, shall have enclosed impellers, and be provided with either an oil or water lubrication system to prevent bearing wear during pump startup. Discharge heads shall be fabricated steel with a stuffing box for packing.
Pumps. 1. Check mechanical seals for cleanliness and adjustment before running pump.
2. Inspect shaft sleeves for scoring.
3. Inspect mechanical faces, xxxxxxxx, and seal rings. Replace if defective.
4. Verify that piping system is free of dirt and scale before circulating liquid through pump.
Pumps. Pumps shall be of the horizontal centrifugal, submersible or vertical turbine type. Pumps should be rated at or near the maximum efficiency for that pump to deliver water. Line shaft deep well turbine pumps shall be water lubricated. Petroleum based lubricated lineshaft pumps will not be permitted.
Pumps. For the purpose of this Drainage Maintenance Plan, fish bearing waters shall be defined as any part of a natural watercourse, marine water body, managed watercourse with headwaters (green) and that part of a managed watercourse without headwaters (magenta) or artificial watercourse (yellow) that is within 300 feet of a functioning tidegate or floodgate confluence with a natural watercourse, marine water body or managed watercourse with headwaters (green). Surface water pumps in fish bearing waters as defined above shall be fitted with a screen or otherwise be approved by WDFW per RCW 77.55.040, 77.55.070, 77.55.310 and 77.55.320. Within five years from the effective date of the Drainage Maintenance Agreement, incorporating the provisions of this Drainage Maintenance Plan, each pump facility in fish bearing waters as defined above that is owned, operated and maintained by DID #18 shall be in compliance with the pump screening provisions stipulated in the General Hydraulic Project Approval (GHPA) issued to the district specific to the Drainage Maintenance Agreement and this Drainage Maintenance Plan. In the event that the established pump screen criteria cannot be met, the Drainage Maintenance Plan shall be modified within 5 years from the effective date of the district’s Drainage Maintenance Agreement to identify a mutually acceptable alternative technology that meets or exceeds these criteria and a mutually acceptable strategy and timeline for implementation.
Pumps. This section covers the design, manufacture, testing, delivery, unloading, and erection of fuel oil pumps, water pumps, sump pumps and other miscellaneous pumps required for the project. The pumps shall be furnished complete with motors, couplings, guards and baseplates. Equipment, material, design, fabrication, inspection and testing shall comply with applicable industry codes, standards and specifications including, but not limited to, ASME, ANSI, AWS, NEMA, NEC, HI, and OSHA. Pumps and equipment shall be selected and designed, including heads, capacities and margins, based on the Contractor's piping arrangement, system requirements and type of fluid being handled. The materials of construction of the pumps shall be compatible with the fluid pumped. The Contractor shall be fully responsible for the applicability, quality and compatibility of these materials. The selection of the pumps shall be subject to Owner's approval. Similar parts of duplicate pumps shall be completely interchangeable. Equipment and piping arrangement, and nozzle orientation, shall be selected for ease of maintenance and to minimize the dismantling or removal of piping and electrical connections for maintenance. Shafts shall be accurately ground and polished throughout their entire lengths and furnished with shaft sleeves. They shall be designed so that the critical speed will not occur within a safe margin of operating speed of the pump. Casings and nozzles shall be designed to withstand a minimum of 1 1/2 times the pump shutoff pressure. Wear rings for casing and impellers shall be replaceable. In general pumps shall have mechanical seals. Where packing is utilized the stuffing boxes shall be integral with pump casing and furnished with lantern rings and leakoff piping. Pumps shall be subject to shop inspection and manufacturer's standard shop tests. The pumps, motors, baseplates shall be thoroughly cleaned, primed and finish coated with manufacturer's standard procedures and paint. Aluminum, galvanized steel and stainless steel surfaces shall not be painted. Equipment shall be furnished with permanently mounted non-corroding metallic name plates.
Pumps. The contractor shall provide FLYGT pumps of the size and configuration as required and ordered by the County.
Pumps. All three phase motor drives for pumps shall be checked for proper rotation prior to being coupled to the applicable pump.
Pumps. All pumps shall be designed for continuous operation unless otherwise specified. All pumps shall be installed in positions convenient for operation and servicing. Where multiple pump installations are required, each pump and its associated equipment shall be arranged in such a manner as to permit easy access for operation, maintenance, and pump removal without affecting plant operation. Lifting lugs, eyebolts, and other special tackle shall be provided to permit easy handling and removal of the pump and its components. Standard types of pumps shall be used wherever possible. Only proven products and models are to be supplied. Strainers (startup or permanent) shall be installed in the suction piping of horizontal pumps or sets of pumps. The driver shall be mounted on an extension of the pump bedplate and shall drive the pump through a flexible coupling with OSHA coupling guard. Pumping systems with variable flow requirement shall have a recirculation line for pump protection. As a minimum, pumps with motors rated for 25 hp and above shall be supplied with a recirculation line for protection. The recirculation line shall normally be routed to the source from which the system takes suction. Modulating or two-position automatic recirculation valves or restriction orifices shall be used as applicable. For the boiler feedwater pump, a modulating automatic recirculation control valve or combined recirculation/check valve shall be used. Pumps furnished for each application shall be sized to accept an impeller at least 1/8 inch larger in diameter than the impeller specified without having to change the pump casing. Vent and drain plugs shall be fitted, where necessary, at suitable points on the pump casing. Oil system pump vents and drains shall be provided with valves. Horizontal split-case pumps shall allow the removable half casing and impeller to be withdrawn without disturbing any of the process piping or valves. Horizontal end-suction pumps shall allow the impeller to be withdrawn from the motor end without disturbing the motor or discharge piping. Where part-load (e.g., two 50%) duplicate pumps for the same service are provided, they shall be capable of operating in parallel.
Pumps. Below is a list of pumps that are faulty and require to be replaced. There are no existing drawings therefore the bidder is required to price for the complete unit. The mechanical scope includes the replacement of the piping at the Aquarium which spans for approximately 1000m.

Pumps i. Recirculating stainless steel pumps with stainless steel impellers and face seals with stainless steel metal components and ceramic seats. Readily removable motor/impeller assemblies permit quick inspection. The pumps are self-draining. All piping distributing water to the upper and lower wash arms is stainless steel tubing.
