Jiangsu Haishi Pump Manufacturing Co., Ltd.

Haishi describes a 1977 origin involving the petroleum/chemical pump division of Shanghai Pump Factory and Jiangsu Xinya Chemical Machinery. Its corporate page identifies casting, machining, sheet-metal work, assembly, testing and physical/chemical inspection functions. These are manufacturer-published descriptions of the production organisation; specify the inspection records and witness points needed for the actual order.

The catalogue also lists BB/OH process constructions, submerged pumps, magnetic-drive and fluoropolymer-lined directions. A corrosive-liquid enquiry should therefore define composition, concentration, temperature and solids before choosing a construction or material. A broad catalogue material list does not establish chemical compatibility for a particular mixture.

HCZ is a horizontal, single-stage, single-suction chemical pump. The family page lists flow up to 2,000 m³/h, head up to 160 m, working pressure 2.5 MPa and a −80 to +300°C temperature envelope. These belong to different sizes, materials and seal arrangements across the family. They do not describe one interchangeable pump operating at all four limits.

The dimensional reference is DIN 24256 / ISO 2858. The page also describes a design basis referencing API 610 eighth edition and VDMA 24297. For an API-specified purchase, put the required edition, construction and deviations into the offer review; the catalogue reference alone is not acceptance to a current project specification.

The HCZ65-160 A row provides a useful comparison. At 2,900 r/min it lists 100 m³/h at 32 m, NPSH 3 m and efficiency 74%. Its density table gives 15, 18.5 and 30 kW for density ratios 1.00, 1.35 and 1.84. Keep the hydraulic point, impeller designation, density and listed motor rating together. A water-based motor choice cannot simply be carried over to a denser chemical.

For the same A designation at 1,450 r/min, the table instead lists 50 m³/h at 8 m, NPSH 1.5 m and efficiency 68%. Supply the intended speed and frequency rather than asking for the frame designation alone. Request the selected curve and allowable operating range for the actual liquid.

The HCZ description offers packing and several single- or double-mechanical-seal arrangements. It describes pressure balancing at the seal through an auxiliary impeller or balancing holes. Ask for the selected seal construction, face/elastomer materials and required cooling or support services against the liquid, temperature and pressure.

The bearing frame, shaft, impeller and stuffing-box region form a removable assembly. The published maintenance arrangement allows work without disconnecting the casing from the pipework; retaining the motor in place depends on an extended coupling. Agree the coupling type, withdrawal clearance and lifting access in the general arrangement drawing.

Published flange options include PN16 and PN25 depending on material, with other connection references also mentioned. Establish the actual flange standard, rating and mating dimensions on the quoted unit. A maximum family working pressure does not establish the pressure-temperature rating of every casing, flange and seal.

For an existing HCZ replacement, send the full nameplate, impeller designation, connection dimensions, shaft/coupling and seal details. Similar frame dimensions do not by themselves establish compatibility with the installed chemical or the existing motor.

HXK is a rotating-case pump, also described as a pitot pump. The rotor/drum and liquid rotate, while a fixed collection tube extends towards the drum perimeter. The manufacturer places the mechanical seal at the lower-pressure inlet side. Establish the inlet conditions and the complete high-pressure assembly rating rather than treating the inlet seal arrangement as a guarantee for every liquid.

The code example HXK300-S1 identifies the HXK family, the 300 drum code and S1 collector-tube code. The model table lists HXK300-S1 at 1–8 m³/h, 135–430 m head, 2,900–4,850 r/min and NPSHr 1.3–1.8 m across its envelope. Those are selection ranges, not simultaneously available endpoints; obtain the curve at the chosen speed.

The family describes belt, frequency-control and speed-increasing gearbox routes. Identify which drive is included, the required motor/frequency and the permitted operating speeds. The quoted package should include guarding, alignment, base and the relevant lubrication/maintenance instructions.

Describe vapour pressure, available inlet pressure, temperature, viscosity, solids and the full operating range, including start-up and low-flow conditions. Ask for the permitted minimum flow and protection settings for the selected assembly. A smooth curve rising towards shut-off does not establish permission to operate indefinitely with the discharge closed.

FJX is a low-head axial-flow direction for forced circulation in evaporators, crystallisers and reactors. Published applications include phosphate-related processes, vacuum salt production, alumina and caustic soda. These applications identify where to investigate the range; fluid chemistry and crystals determine the actual construction.

The FJX250 row lists 250–600 m³/h, 1.5–5 m head and 740–1,450 r/min. The series text publishes 1 MPa gauge working pressure and temperature up to 170°C. Have the selected casing, seal and materials confirmed for the design pressure and temperature; loop head is different from the pressure contained in the system.

The described construction uses an adjustable blade angle, belt-speed adjustment, a quick-fitting double mechanical seal and water-cooled oil-lubricated bearing regions. Specify the selected transmission, blade setting, seal support and available cooling-water services. Do not assume that the photograph establishes every accessory supplied.

For evaporation or crystallisation, give operating pressure, temperature, vapour pressure, solids/crystal size and concentration, and the lowest liquid level or suction head. Supply the real loop and heat-exchanger losses at the circulation flow. Request a suction/NPSH review for the selected operating point, including start-up and concentration changes.

The FJX-T page offers titanium, Hastelloy and other special-material directions for the evaporator loop. Specify the exact wetted grades, chemical analysis, concentration, temperatures and solids rather than ordering only “titanium pump”. Obtain the agreed corrosion/material basis and any material inspection records required by the project.

The same page describes three different arrangements: a suspended pump under the circulation pipe, an adjustable spring-supported base and a casing-free internal circulation construction. These are alternatives with different equipment and civil interfaces. Select the arrangement in conjunction with the evaporator supplier.

The manufacturer describes suspended and spring-supported arrangements as ways to accommodate movement and potentially remove an evaporator expansion joint. For a real plant, request the allowable nozzle loads, support movements, spring setting and complete piping/support drawing. An expansion joint should only be omitted when the agreed engineering design permits it.

Agree access to seals, bearings and internal components, the isolation/draining arrangements and replacement lifting route. Include seal/cooling services and responsibility for supports, pipework and field alignment in the quotation, especially where the pump is integrated into the evaporator structure.

Haishi also describes nuclear-pump work. A National Nuclear Safety Administration decision dated 26 November 2018 identifies this exact legal company and renewed design/manufacturing licences with validity through 31 December 2023. The issuer’s June 2023 holder list records pumps at nuclear safety class 3. These are dated historical records, not a current approval badge or approval for the HCZ, HXK and FJX constructions above.

A nuclear-safety purchase needs the current licence, permitted activity scope, exact equipment classification and project quality/inspection documentation checked for the order. Ordinary process-pump buyers should similarly agree the applicable standard edition, selected curve, hydrostatic/performance tests and material/seal documents in the offer.
