Corrosive-liquid transfer · lining, solids and suction arrangement · Changzhou
Jiangsu Wofulong Pump & Valve Co., Ltd.
Wofulong’s chemical-pump range combines fluoroplastic-lined clean-liquid pumps with a separate wear-resistant slurry direction. Start with the chemical composition, temperature and solids, then the suction arrangement. These details determine whether magnetic drive, a mechanical seal, self-priming or a slurry construction is worth evaluating.

First separate clean corrosive liquid from corrosive slurry
| Your liquid and installation | Catalogue direction | Selection question |
|---|---|---|
| Clean corrosive liquid without particles or crystals; shaft-seal containment concern | CQB fluoroplastic magnetic drive | Which lining, bearings, static seals and dry-run/temperature protection suit the actual chemical? |
| Clean corrosive liquid; conventional centrifugal installation | IHF fluoroplastic centrifugal | Which mechanical seal, lining, material temperature limit and coupling arrangement are offered? |
| Clean corrosive liquid drawn from below the pump | FZB fluoroplastic self-priming | What are the lowest liquid level, suction losses, initial-fill requirement and achievable priming conditions? |
| Corrosive liquid containing abrasive solids | UHB-ZK wear-resistant slurry direction | What are particle size, solids mass fraction, settling behaviour, seal and flushing requirements? |
CQB: specify the containment parts and protect the wetted bearings
The CQB fluoroplastic description uses magnetic transmission through a stationary containment shell. It lists lining/material directions including F46, PTFE and PFA, with optional temperature, dry-running and leakage monitoring. Ask for the exact material of casing lining, impeller, containment shell, bearings and static seals; “fluoroplastic” alone is not a complete material schedule.
The supplier’s conditions prohibit dry running and liquids containing particles or crystallised material. Include tank-emptying events, interrupted suction and any crystallisation on cooling in the enquiry. Agree the protective instruments, stopping logic and cleaning/restart procedure for the selected pump.
A concrete catalogue example is CQB50-32-160F: at 2,900 r/min and a reference liquid density of 1,000 kg/m³, the table lists 12.5 m³/h, 32 m head and a 4 kW motor, with 50/32 mm inlet/outlet connections. This is one tabulated selection, not a guarantee for a different concentration, density or viscosity. Obtain the issued curve and selected motor for your actual liquid.

IHF: lining and seal selection still need the actual chemistry
IHF is described as a horizontal fluoroplastic centrifugal pump with a metal-supported lined casing and fluoroplastic hydraulic parts. The documentation distinguishes long-bracket coupled and short-bracket close-coupled arrangements, and describes mechanical-seal face options. Confirm the offered arrangement and each seal-face/elastomer material against concentration, temperature and operating cycle.
The product text distinguishes a −20 to +120 °C temperature direction from special-material higher-temperature configurations. Do not specify a high-temperature unit only from the page’s broad headline. Request the offered lining, seal and pressure–temperature limits and the model’s current documentation.
For replacement work, compare the complete assembly rather than only the inlet/outlet sizes. Provide the existing nameplate, foundation and pipe drawings. Agree nozzle locations, flange standard, shaft height, coupling/guard, alignment procedure and maintenance access before confirming interchangeability.
| IHF50-32-160 catalogue condition | 2,900 r/min | 1,450 r/min |
|---|---|---|
| Reference liquid density | 1,000 kg/m³ | 1,000 kg/m³ |
| Listed flow | 12.5 m³/h | 6.3 m³/h |
| Listed head | 32 m | 8 m |
| Listed motor power | 4 kW | 0.55 kW |

FZB: self-priming still starts with liquid in the pump
FZB’s description explains a liquid-storage and gas/liquid separation arrangement: retained liquid mixes with suction-line air, air leaves through the discharge and liquid returns inside the pump. Ask for the initial-fill volume and procedure, discharge arrangement during priming and restart instructions for the offered size.
The catalogue cites suction lift up to 4 m. That figure is not a site-specific promise for a hot volatile chemical through a long pipe. Provide the lowest source-liquid level, pump elevation, suction length/diameter, fittings, temperature and liquid vapour properties. Obtain the achievable lift and priming time for the actual installation.
The page prohibits dry running and liquids containing particles or crystals. Its seal directions include a single-face mechanical seal and optional alternatives. Specify which seal and auxiliaries are included, and identify a liquid-level or other protection arrangement for loss of source liquid.

UHB-ZK: write the solids specification in measurable terms
UHB-ZK is presented as a corrosion- and wear-resistant centrifugal direction using metal-supported ultra-high-molecular-weight polyethylene (UHMW-PE). Its detailed description gives solids concentration up to 20% by mass and particle diameter up to 1.0 mm. These conditions distinguish it from the clean-liquid CQB/IHF/FZB directions; they do not establish suitability for every abrasive mineral or chemical.
Provide particle-size distribution, hardness/shape, solids mass fraction, density, viscosity, settling behaviour and temperature. Explain whether the pump starts with settled solids, feeds a filter press or operates over changing backpressure. Ask for a selected curve and power requirement at the actual slurry conditions.
The catalogue names K-type dynamic sealing and mechanical-seal directions. Confirm the offered seal, any flushing supply, start/stop leakage handling and replacement parts. Its general temperature statements vary across the page, so obtain a written limit for the exact lining and configuration rather than assuming a blanket high-temperature slurry capability.

Coordinate pump, lined valves and piping without assuming one material fits all
The company profile identifies 江苏卧氟龙泵阀有限公司 in Changzhou and includes chemical pumps, lined valves and piping, with fluoroplastic, engineering-plastic and metal material directions. Its stated support includes selection, installation and commissioning. For an overseas order, agree the actual seller/manufacturer, scope of technical support and destination-specific documentation in the commercial offer.
A pump and its adjacent valves, pipe lining, gaskets and instruments need a consistent chemical and temperature specification. Request a parts-by-parts material schedule and connection standard for the offered package. Do not infer compatibility of a whole process system from the casing-lining name.
Company identity was cross-checked against a certification issuer’s historical published organisation record. A historical record does not establish today’s certificate status or model approval. If the purchase requires a management-system certificate or a product approval, request its current issuer status, entity/site scope and applicable product documentation with the offer.
