SZPL Vertical Slurry Pump — The Vertical Build of the SZP Series
Vertical version of the SZP series for sump and pit duty. Single-stage single-suction axial-suction centrifugal, with three sealing arrangements and two bracket structures.
SZPL is the vertical build of the SZP series — the same single-stage, single-suction, axial-suction hydraulic design mounted for sump and pit duty rather than on a horizontal baseplate.
- Vertical version of the SZP series; horizontal version is SZP
- Single-stage, single-suction, axial-suction centrifugal
- Solids concentration by weight: ash and coal slurry to 45 %; ore slurry and dense medium to 60 %
- Three sealing arrangements — expeller plus packing, packing alone, or mechanical
- Split or cylindrical bracket; thin-oil or grease lubrication
- Water cooling fitted from 150 mm size upward on thin-oil builds

Where It Is Used
The series carries slurry containing solid particles across power generation, metallurgy, coal and building materials — hydraulic ash removal in thermal power plants, ore slurry transport in concentrators, and coal slurry and heavy medium transport in coal washing plants.
The vertical arrangement suits positions where the pump hangs into a sump or pit rather than sitting on a floor-mounted baseplate.

Model Performance Data
Clear-water performance for the models below. Ratings are per speed; three duty points are shown for each. Other sizes in the range are available — send your duty point and we will issue the matching curve. The 150SZPL at 590 r/min is a belt-driven arrangement; the others are direct coupled.

Sealing Arrangements
Three arrangements are available, and the choice decides whether the installation needs a seal water supply.
- Expeller plus packing combination — stuffing box, auxiliary impeller, water seal ring, packing, packing gland and shaft sleeve.
- Packing seal — stuffing box, spacer sleeve, water seal ring, packing, packing gland and shaft sleeve.
- Mechanical seal — seal box, spacer sleeve, mechanical seal, gland and shaft sleeve. ⚠ Seal water must be supplied; running dry will burn out the seal.
Bracket and Lubrication
Two bracket structures are available: horizontally split and cylindrical.
- Split bracket, thin-oil lubrication — bracket body and cover, shaft, bearing housing, bearings, bearing gland and sleeve, oil seal, water retaining plate and release collar. From the 150 mm size upward a water cooling device is fitted.
- Split bracket, grease lubrication — adds an embedded cover and grease cup, and omits the water cooling device.
- Cylindrical bracket — grease lubricated.
⚠ On thin-oil builds, oil must be filled to the level shown on the gauge before start-up. Running without oil overheats and damages the bearings.
Before You Start the Pump
- Motor rotation must match the arrow on the front casing. Test the motor separated from the pump; reverse rotation damages parts.
- Packing must be installed before operating.
- On mechanical seal builds, confirm the seal water supply is running.
- On thin-oil builds, confirm the oil level before start-up.
What to Send With Your Enquiry
Send the flow and head, the slurry analysis with solids concentration by weight and particle size, the pit depth and mounting arrangement, and whether seal water is available. We will confirm the model, the sealing arrangement and the bracket build, and issue the performance curve with the quotation.

| Relation to the SZP series | SZPL is the vertical build; SZP is the horizontal build. Same single-stage, single-suction, axial-suction hydraulic design |
|---|---|
| Construction | Single-stage, single-suction, axial-suction centrifugal, mounted vertically for sump and pit duty |
| Casing | Bimetallic — cast iron outer shell (HT200 or QT500-7 according to working pressure) with a high-chrome inner shell |
| Impeller | Closed, three to six twisted vanes, high-chrome alloy cast iron; eight back vanes on each shroud |
| Shaft sealing | Three arrangements — expeller with packing, packing alone, or mechanical seal |
| Bracket and lubrication | Split bracket (thin-oil or grease) or cylindrical bracket (grease). Water cooling is fitted from the 150 mm size upward on thin-oil builds |
| Solids concentration by weight | Ash and coal slurry up to 45 %; ore slurry and dense medium up to 60 % |
| Discharge sizes | 40, 50, 65, 80, 100, 150, 200, 250 and 300 mm |

| Typical duties | Hydraulic ash removal in thermal power plants, ore slurry transport in concentrators, coal slurry and dense-medium transport in coal preparation plants |
What is the difference between SZP and SZPL?
Same series and same hydraulic design. SZP is the horizontal build; SZPL is the vertical build for sump and pit duty.
How do I read the model number?
In 80SZPL-A36: 80 is the outlet diameter in millimetres, SZPL identifies the vertical build, A is the number of impeller vanes, and 36 is the impeller diameter in centimetres.
Which sealing arrangement should we choose?
Expeller plus packing where you want to limit seal water; packing alone as the general arrangement; mechanical where leakage cannot be tolerated. Mechanical seals must never run dry.
Thin oil or grease lubrication?
Thin oil for continuous heavy duty, with water cooling fitted from the 150 mm size upward. Grease where the maintenance regime favours it; the grease build omits the water cooling device.
What solids concentration can it handle?
By weight, ash and coal slurry to 45 %; ore slurry and heavy medium higher. Send your actual figure and we will confirm the selection.
